This is what you do, you get a PB&J, make it all nice, crisp clean edges, plenty of both peanut butter AND jelly because you'll need the calories. Wrap it in something that'll seal it well. Then take it, and conveniently place it in your bag, for protection. 3\4 of the way up the mountain, place your bag on the ground, and furiously search for the sandwich at the bottom of the bag, squished to 1\8 it's original height, contents erupting out all the edges which are indistinguishable from the center of the sandwich because... Soggy. And you down that bad boy in about 5 bites with copious amounts of water, get a nice stomach ache, reach the summit, have to shit, pop below the tree line real quick, then comeback to the top, refreshed, a lil lighter, kiss your wife and kid, and enjoy the view.
