Pack Sizes



When my youngest son was about 4, I was in the market for a new backpack. In those days, my thinking was that if big was good, the bigger was better.  I envisioned myself going on treks 7 days at a time with no resupplies.  With this in mind, I was proud to purchase the Kelty Red Cloud 6400 (Big Red). When I bought it, my son could literally ft inside of it.  He is now in his twenties and that is no longer a good idea.  Neither, it seems, is getting the biggest pack you can just because you can. One of the properties of a gas is that it will expand to fill its container.  This is also true of packing.  If you have enough space, you will find something to fill it with.  This led to me giving up trail comfort in favor of camp comfort which is not always a wise exchange.  I used to think that the strange looks I got was because folks were impressed with the behemoth on my back.  Age has taught me that the look was actually more like "Wow. What an idiot.".  This is especially true of thru-hikers that I would see on the Appalachian Trail.   The pack has been good to me, but 20 years of carrying more that any sensible person would has taken its toll on Big Red.

I am now in the market for a replacement, so I am planning to downsize (it would be hard not to).  Packs sizes are often measured by volume using either cubic inches or liters.  No one measures packs by quarts or gallons, but I thought it would be useful in the chart below to give an idea of how much they hold.  Conversions are rounded to the nearest integer.

Bag Type Cubic Inches Liters Gallons Quarts
Drawstring/Cinch Bag 693 11 3 12
School Bookbag 1343 22 6 23
Weekend 2746 45 12 48
Multiday 3967 65 17 69
Extended Trip 4577 75 20 79
Big Red 6400 105 28 111

It seems reasonable that anyone thru-hiking the AT might have a good idea what a good pack size should be.  Here is what a survey revealed from hikers that did that in 2019.

Thru-hikers packs had an average (mean) capacity of 52 liters, but anything between about 43 and 61 liters was common. Thru-hiker pack capacities ranged from 25 to 80 liters.
The top three most common sizes were 55, 60, and 65.

I will post back here after I make my final choice, but I am pretty sure it will be less that 105 liters.


edit: I decided to go with the Osprey Aether AG 70.  At 70 liters, it is no thru-hiker pack, but it is closer to it than it is to Big Red.

To condemn or accept

This past Sunday I heard from two churches I am associated with give seemingly opposing views on the recent gender transition of a public figure.  At "Church A" the pastor stood behind the pulpit and waved and pointed his finger toward the congregation condemning the public praise of such a vulgar announcement.  This, we were told, is yet another example of the Sodom like culture our country as descended into.  Only by rejecting such deviant behavior could our country have any chance at a promising future.  "Church B" posted on their Facebook page that the public figure would be welcome at their church.  Church B is a community church that follows the relevant movement and bills themselves as a "church for people that don't do church".

Both churches are from a Protestant background and both are reading the same Bible, so who's right and who's wrong?  For the sake of argument, let's assume the Bible is the divine word of God meant to direct us toward God and provide the best way to live a God honoring life which is the goal of congregants of both churches.  Those points could be debated, but for the sake of this discussion, let's take them as fact.  Another concept I will defer to discussion elsewhere is using the term 'homosexuality' to cover all aspects of the LGBT community.  For simplicity, I will include them all together for this discussion, but I acknowledge that each part of the alphabet soup is it's own group.

Let's look at Church A's position first.  The  Old Testament is pretty clear.

Leviticus 18:22 - Do not lie with a man as one lies with a woman; that is detestable.

Leviticus 20:13 - If a man lies with a man as one lies with a woman, both of them have done what is detestable. They must be put to death; their blood will be on their own heads.

You will hear some say that they Old Testament has lots of rules and laws that we no longer find convenient to follow.  Many see the New Testament as a replacement that supersedes the Old Testament.  If  you were to ignore Matthew 5:17-18 (which is not recommended), there are still plenty of New Testament prohibitions.  Here are the most common:

Mark 10:6-9 - 6 "But at the beginning of creation God 'made them male and female.' 7 'For this reason a man will leave his father and mother and be united to his wife, 8 and the two will become one flesh.' So they are no longer two, but one. 9 Therefore what God has joined together, let man not separate."

Romans 1:26-28 - 26 Because of this, God gave them over to shameful lusts. Even their women exchanged natural relations for unnatural ones. 27 In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed indecent acts with other men, and received in themselves the due penalty for their perversion. 28 Furthermore, since they did not think it worthwhile to retain the knowledge of God, he gave them over to a depraved mind, to do what ought not to be done.

1 Corinthians 6:9-11 - 9 Do you not know that the wicked will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor male prostitutes nor homosexual offenders 10 nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. 11 And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.

1 Corinthians 7:2 - But since there is so much immorality, each man should have his own wife, and each woman her own husband.

1 Timothy 1:8-11 - 8 We know that the law is good if one uses it properly. 9 We also know that law is made not for the righteous but for lawbreakers and rebels, the ungodly and sinful, the unholy and irreligious; for those who kill their fathers or mothers, for murderers, 10 for adulterers and perverts, for slave traders and liars and perjurers--and for whatever else is contrary to the sound doctrine 11 that conforms to the glorious gospel of the blessed God, which he entrusted to me.

Jude 1:5-8 - 5 Though you already know all this, I want to remind you that the Lord delivered his people out of Egypt, but later destroyed those who did not believe. 6 And the angels who did not keep their positions of authority but abandoned their own home--these he has kept in darkness, bound with everlasting chains for judgment on the great Day. 7 In a similar way, Sodom and Gomorrah and the surrounding towns gave themselves up to sexual immorality and perversion. They serve as an example of those who suffer the punishment of eternal fire. 8 In the very same way, these dreamers pollute their own bodies, reject authority and slander celestial beings.

It's pretty clear from these verses that the New Testament as well as the Old condemn homosexuality.  God does not prohibit things at random but rather for our own protection.  Considering these verses and the culture in which we now live, one can not help but be reminded of two other verses:  

 Judges 21:25 - “In those days Israel had no king; all the people did whatever seemed right in their own eyes.”

Isaiah 5:20  - “Woe to those who call evil good and good evil, who put darkness for light and light for darkness, who put bitter for sweet and sweet for bitter.”

Billy Graham once said “We have changed our moral code to fit our behavior instead of changing our behavior to harmonize with our moral code. [...] But right is right even if nobody is right, and wrong is wrong even if everybody is wrong. God does not change the moral law to suit our behavior.”

Based on the above, it is easy to see where Church A is coming from.


Now let's look at Church B's position.  Consider the following New Testament verses:

Matthew 6:15 - But if you do not forgive men their sins, your Father will not forgive your sins.

Matthew 7:1 - Judge not, that ye be not judged.

Matthew 9:13 - Then he added, "Now go and learn the meaning of this Scripture: 'I want you to show mercy, not offer sacrifices.' For I have come to call not those who think they are righteous, but those who know they are sinners."

Mark 12:29-31 - 29 “The most important one,” answered Jesus, “is this: ‘Hear, O Israel: The Lord our God, the Lord is one. 30 Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’ 31 The second is this: ‘Love your neighbor as yourself.’There is no commandment greater than these.”

John 8:7 - And as they continued to ask him, he stood up and said to them, “Let him who is without sin among you be the first to throw a stone at her.”

Romans 3:10 - As it is written: There is no one righteous, not even one.

Romans 3:23 - For all have sinned, and come short of the glory of God;

James 4:12 - There is only one Lawgiver and Judge, the one who is able to save and destroy. But you--who are you to judge your neighbor?

It would seem from these verses that, like Church B, we should accept everyone with open arms.

So which is it?  The Bible tells us in no uncertain terms that homosexuality is a sin.  It is equally adamant that we are to love more so than judge our neighbor.

Is it possible that both churches might be right?  Looking at all of the verses above and indeed the Bible as a whole, it seems to me that four points emerge.

  • There is a such a thing a "sin" which is defined as violating God's law.
  • We all sin.
  • God hates sin.
  • God loves us in spite of our sin.

To reconcile His hate of sin, and His love for us, God sent Jesus to die on the cross to forgive us of our sin.  This forgiveness is available to us all if we will but accept it by confessing our sins and acknowledge Jesus as Lord and strive to follow after Him.

Since God has forgiven us, we should not only turn from sin and turn toward God, but we should also speak the truth in love (Ephesians 4:15) while also being slow to judge (Matthew 18:21-35).  The phrase "hate the sin, but love the sinner" gets lots of ridicule sometimes, but I believe it is an accurate portrayal of God's love toward us.  I believe anyone that tries to paint God as "all love" or "all judgement" is only painting half the picture. He is both. 

While I do believe homosexuality is a sin and thus wrong, I also know that I myself have sinned many times and am no more righteous that anyone else.  We cannot attract others to God by screaming and yelling or by pointing our fingers.  Only by attempting to mirror the love of Jesus will we attract others to God and He alone can convict them of their sin and help them to turn from it.

The Average Running Pace

When one first starts running or walking, just finishing a certain distance is an accomplishment.  At some point, however, most runners will eventually want to finish the same distance in a given time … and then beat that time.  This paper looks at four races (5K, 10K, Half Marathon, and Marathon) to determine what an average running pace is. The data for this came from four races in Atlanta, GA

5K - 3.1 miles - 9/22/2016 - KP Corporate Run/Walk

Half-Marathon - 13.1 miles - 3/20/2016 - Publix Georgia Marathon & Half Marathon
https://results.chronotrack.com/event/results/event/event-12972

Marathon - 26.2 miles - 3/19/2017 - Publix Georgia Marathon & Half Marathon
https://results.chronotrack.com/event/results/event/event-20420

For this study, the participant count includes all participants whereas runner count only includes those who finished with a  15 minute/mile pace or better.  It is acknowledge that a 5K in South Florida will have a different pace than a Marathon up Pike's Peak.  In Atlanta, GA, the terrain is moderate with some rolling hills and all four races where in the same general area.  With this terrain, it would be hard classify anything slower than 15:00 as a "run".

Every runner has aspirations of beating their own time or achieving a Personal Record (PR).
Some runners additionally have a competitive spirit and want to be “above average”.

Note: The average of the averages is 10:46.

Being above average does not mean that a runner was in the fastest 50% .

The average is 8:45, but to be in the top 50%, the runner needs a time of 7:00 or better.

 Note: The average 50% pace is 10:39

As a runner advances from one distance to the next, one might expect the pace to slow.  This was not always the case.  Using the same races, there were 482 runners that ran that ran a 5K and then later ran a 10K.  There were 190 runners that ran a half marathon followed the next year by a marathon.  There were only a very few that ran a 10K followed by a half marathon, so their results are not shown here.



In most cases the pace difference between two races was 3:00 or less.

Hearing The Still Small Voice

If you are reading this (or having it read to you), then you and I have something in common - we are aging.  For the young, this means getting stronger, gaining new abilities, and learning new things.  For the old, this means getting weaker, losing abilities, and forgetting things.  Many have observed that "getting old sucks" and that it is not for the faint of heart.  I have always been inspired by the adage: "You can cannot always control what happens to you, but you can always control how you respond".  This has never been more evident to me than when I read the writings of Horace LaFavor.

When I was in middle school, Coach LaFavor was the PE teacher.  I was never much of an athlete in my middle school years, so he did not really "coach" me in anything, but we all called him Coach.  My mother worked at the school so I saw him slightly more than I would otherwise.  He and I were not all that close, but I always liked him well enough.

Since retiring some years back he and his trusty sidekick have become fishers of men as well as fishers of carp (he would be upset if I reversed the two).  In addition to loving God, his wife, his hound, and fishing, he also loves to write (which is how I know about his first loves).  He has probably served more as Coach to me through his writing than he ever did in a middle school gym.

The other day, one of his pieces drew my attention more than others.  He and his family have faced many struggles and he has always shared them with a "peace that passeth all understanding",  This most recent struggle was comparatively insignificant, but for some reason to me every bit as powerful.  I hope that as I get older, I am able to look at life with the same long view and have the same positive and spiritual perspective as Coach.  With his permission and without further ado, here is the piece that got my eye:

======================

Wednesday Thoughts- 1/20/16
It is 4:00 AM and I cannot sleep. When I cannot sleep it is usually caused by the anticipation of an upcoming event or eating too much Pizza or Mexican food the night before. When this situation occurs I often get up and write. I know it isn’t Sunday but with your permission, I’d love to share with you some “Wednesday Thoughts”……………………….
I have reached yet another milestone in my life. After being “encouraged” by my family and close friends to have my hearing tested I recently broke down and went in to see what they could do for me. There were several tests administered but the first one was the clincher for me. Ramona was asked to come (as a familiar voice) and she was given a list of 25 very simple one syllable words to read out loud to me. My task from approximately 15 feet away was to repeat each word back to her. As I approached the sixth or seventh word and saw the tears coming down my precious wife’s face I made the brilliant deduction that I wasn’t doing very well on this test. Bottom line is that I couldn’t clearly hear the voice of my precious wife of over 42 years. In fact, I only identified 10 out of 25 words correctly.
This coming Sunday morning I have been invited to speak to the Men’s Breakfast group at Poplar Springs Baptist Church in Hiram, Ga. We will be talking about voices. We will begin with voices such as Willie Nelson, Nat King Cole, Merle Haggard and Elvis but soon and very soon we will settle and stay on the topic …”The Voice of Jesus.”
Jesus has been speaking to many of us for years from just a few feet away but for some reason we have not heard or at least not properly responded to His voice. Maybe time has caused our ear drums to become hard and calloused but more likely than not, sin has blocked our ear canal like so much nasty ear wax.
This past week the administrator of my hearing test put some hearing aids in my ears and for the first time in years I could actually hear!!! It was a freedom that I didn’t realize I was missing. It was wonderful but to obtain this new found freedom a very high price had to be paid.
Perhaps Jesus is speaking to you this morning. He can clean your ears and make your hearing better than ever! He can show you a freedom and peace that you didn’t even know you were missing! This freedom however is eternally expensive but dear friends I am here to tell you that Jesus has already paid the price! Listen to the voice of Jesus this morning. It will be clear as crystal and He will never lead you wrong. And the price is right. The price was paid with His blood on the cross…....paid in full.

What would Gunny Say?

In the Army, they are known as "Drill Sergeants".
In the Navy, they are known as "Recruit Division Commanders".
In the Air Force, they are known as "Military Training Instructors".
In the Marines, they are known "Drill Instructors".

Those who have served know what they are like.  Those who have not have properly seen them depicted in movies or television.  Probably the most iconic is Gunnery Sergeant Hartman (R. Lee Ermey) in the 1987 film "Full Metal Jacket".  Ermey was an actual Marine Corps Drill Instructor in 1965-1967.

Having been to Marine Corps boot camp myself, I can attest to the fact that his portrayal of a drill instructor is spot on as is the portrayal of boot camp overall in the movie.  Boot camp serves a very specific purpose.  To train young men and women into Marines.  While every Marine has their own military occupational specialty (or job), they are all considered to be "a rifleman first".  The yelling, screaming, fast pace, and attention to detail are all intended to prepare a Marine for the very real possibility of combat.  They are no longer children, but are now men and women prepared to place themselves in harms way for God and Country.

I have little doubt that Gunny Hartman would agree with the many posts, videos, and memes that have mourned the loss of the resilience of our youth.  I am sure you have seen them.  They denounce the overuse of everything from bicycle helmets to anti-bacterial soap.  They all state the kids growing up in the [insert decade here] were tougher than kids of today.  I am sure Gunny would agree.

As I write this, my son is at Marine Corps boot camp right now.  I have recently learned of another practice that would have Gunny shaking his head in dismay.  Marines graduate on most Fridays.  This means families are on base Wed-Fri taking pictures of any recruit they see.  They then post these pictures to a common Facebook page and parents at home commence to playing "Where's Waldo" as they try to find their young recruit in the sea of look-a-likes (not unlike what happened when many of them were at summer camp when they were much younger).  In addition to Waldo pictures, these pages are filled with parents supporting each other and wondering how they are going to make it until their baby comes home briefly before going out again.  Gone are the days when the recruits shipped off and Mom and Dad got maybe a letter or two before graduation.  Now we have Facebook where Mom can see her little baby marching around the base.  I think it is time some of these parents land the helicopter and let their babies go... just a little bit.  I have to wonder "What would Gunny say?"

Now, if you will excuse me, I have to go find my Waldo.

Pursued


The other day I was watching a crime show on tv.  The detective saw the suspect in the park.   He observed him for some time before approaching.  He then approached the suspect and said he would like to speak with him.  The suspect then gave chase and ran into an apartment building nearby.  The detective pursued right behind.  The suspect climbed the stairs and soon found himself trapped on the roof.  Fearful of what might happen if the detective caught him, he decided to try and jump from one roof to the next.  His attempt failed and he wound up hanging for dear life to a pipe near the top of the first building.  He cried for help.  The detective approached and tried to reach out to assist him.  The suspect was wearing a backpack.  The detective told him that the backpack was weighing him down.  He advised him to let the backpack go, but the suspect refused.  The suspect tried to reach up the detective, but restricted by his backpack, he was unable.  He soon lost his grip and fell to his death.

Afterwards, I could not help but think about how this is really of picture of God's desire for relationship with us.  So often, he will approach us in the park and just want to talk to us.  Just to sit on the bench and have a pleasant conversation.  We, however, are afraid of him and start to run.  Like the suspect, we are afraid of what he will ask us to do, afraid of what he will find out, afraid of what sins he will expose, and afraid of being asked to give something up.  So we run.  We run and try to hide from the one who created the entire universe.  The one who sees all and knows all.  Like an elephant hiding behind a bamboo tree we think we can hide from God.  Like the suspect, eventually our burden of sin causes us to stumble.  Were we to let our sin go, we would find it easier to take hold of God's hand and be drawn to safety.  Clinging to the sin will eventually send us to a certain death.  At this point, the analogy begins to break down.  In the story, the detective tried to reach out to the suspect who was crying for help...but he was unable.   In reality, when we cry out to God, he will reach down and grab us and left us ... with our burden of sin still attached.  Once he has set us safely down, he will take the burden and cast it as far as the East is from the West.  If only we would just stop and talk to him...while we are still in the safety of the park.

Word Search




Here is a Word Search application that I wrote.  You can keep it simple and just key in the words you want to use for the Word Search or you can get fancy and control the settings below:

  • Shape - the shape of the puzzle
  • Directions - which way the words should flow
  • Case - uppercase vs lowercase
  • Filler - what characters to place in the gaps
  • Solution - whether to show or hide the solution
  • Order - whether or not to alphabetize to word list
  • List - show the word list beside or below

This is a windows application (an EXE) and is not a website or browser app.

While there are many applications and websites that will already do this for you, I created this one to solve a developer challenge that has bugged me some time.  Programmatically, what is the best way to fit words into a box and not overlay existing words?

The program is really just a series of nested loops.
Make several attempts to find a place for all the words
  For each word
    For each position in the puzzle (until you find a match)
      For each direction (until you find a match)
        For each letter in the current word
          Place the letter in the spot 
            if the spot is not already taken
            (otherwise try the next direction or position)

The code is a C# .NET Windows Application made with Visual Studio 2012.  If you are interested, you can download the source code.
