What thru-hikers think about

I have been asked this question almost as much as I was asked if I was going to bring a gun. I have about 10 hours a day walking - what do I think about? I'm three weeks in but so far this is what I have been thinking about:

1. Nature and how crazy awesome it is
2. Food
3. Songs
4. Songs about food
My latest is:
A peanut butter tortilla
A peanut butter tortilla
A peanut butter tortilla
With a little granola on top

But on a slightly more serious note: nature and being out here never gets old and one thought always leads to another and pretty soon we are at the shelter to set up camp.

Looking out over a mountain range and seeing all the massive uprooted trees will get me thinking about tree root systems which will get me thinking about the Magic School Bus. Then I will wonder if we still have those at home and how i will find it when i get home and see the episode/chapter one where they went through the body and used cells as inner tubes to dodge all the organs. Then it reminds me of Indiana Jones and I start thinking about that.

Long story short: every thought ends with Indiana Jones.
