Bean Bark...a website that has recipes on dehydrating meats, fruits, and vegetables so you can take them backpacking/camping. You reduce the weight of the food for easy backpacking and then rehydrate at the campsite. Wish I had seen this website YEARS ago!
Some interesting ideas about dehydrating for hiking and camping. Not entirely sure all of these are safe. (For example, is it really okay to dehydrate meat without turning it into jerky?)
Dehydrate your own food using a dehydrator? If the power goes out, they say to use a vehicle to keep the bugs out. On a hot day, put oven racks of food inside and let them dry in the sun.
