I sometimes wonder if this is actually a group of ex-cons that learned how to make the most out of what was available in a 6' x 8' jail cell.
I can imagine you're walking down the trail and there's any old piece of trash on the side... say... a tennis ball can. Your first thought is - geez, some crazy nut carried this thing all the way up this hill and then left it on the side of the trail! Not only that, but maybe 100 hikers have walked by it and left it there. This is nuts!
You're not thinking of litter or inconsiderate people. You're wondering how anyone could pass by a perfectly good tortilla container that you could in fact also store water, first aid supplies, a telescope, camera monopod, and start fires using magnification of the suns rays.
In fact, before you arrived there was just a tennis ball can. After you left the can is gone and there's a pile of 8 pieces of gear from your backpack that you threw on the ground which you no longer needed after you picked it up.
I can imagine being in a shelter and one of you keeps staring at me. About midnight your friend holds me down and you proceed to forcibly pull my belly button lint out and make a run for it down the trail because you think it's a better, lighter emergency firestarter than an esbit tablet!
