I once went on a backpacking trip with a couple who picked me up hitchhiking. The guy told me his pack weighed 90 lbs, and I believed him when I tried to pick it up. Man! Among other things, he had a small pressure cooker to cook their dry beans. And this was for a 4 day trip. But you know what, that guy hiked so fast that it killed me to keep up with him on the trail.
