After the "24 hour ration packs" thread I got to thinking about food. I know a lot of you guys like to hike, what kind of foods do you carry with you when doing, lets say, a 5-15 mile hike. What do you carry to eat during the hike? Do you carry some other kind of food with you seperate just for survival use? Also, how much water do you usually carry with you, and do you mix something in your water? I have heard a pinch of salt in your water is a bit good for hiking?
