Last Summer I went to the George Washington NF with a few friends, and friends of friends, to pack. We climbed to the top of Mill Mountain, which is a steep climb but no more than 1/2 a mile. Anyway, one guy brought a school bookbag which he attached a cot to, with a jar of moonshine, almost no food ( I had to feed most of the people on this trip) and a sleeping bag. The cot and sleeping bag were tied to the outside of the pack but not tightly, they would swing like a pendulum. He kept asking why his pack felt so awkward. I just tried to keep a straight face and explained that loose objects are no good. I must admit, however, that his moonshine was a very nice addition to the evening.
