Everything tastes better when you're camping. I suspect it's more than just being hungry or alive. I think the outdoor air has something to do with it. The extra activity gives you an appetite. There are probably a lot of things that go into it.
I noticed once that Colorado's "junk food" tastes a lot better than the stuff we have in Alabama and that mystified me. It was suggested to me that the higher altitude causes things to spoil less quickly (food starts spoiling as soon as it's created) and that food is just fresher at the higher altitudes.
