My first backpacking trip when I was 12 was me, a bunch of other kids, and two 20-somethings who were supposed to "take care" of us, but that's a misleader because they were both as dumb as we were.
Naturally, being all cool and stuff, we packed in all the ingredients for bacon cheesburgers. Yeah, that's right. Double bacon cheeseburgers at that. It was awesome until we realized they attracted every bear in a 5 mile radius. Needless to say that was an...interesting night
One the same trip I ate a ham, cheese, lettuce and mayo sandwich that had been in my pocket for 3 days. The lettuce was brown.
