This is not mine. I saw somewhere else and thought someone might like to try it out. I guess we've all seen the Les Stroud videos where some of his coldest nights were when his fire went out because he fell asleep. This kind of thing might solve the problem. So, try it out and report back. **If you haven't tried it out and have an opinion, how about just keeping it to yourself. It would be nice if SM got back to "knowledge sharing based on actual experience" instead of "opinion-as-fact op-eds."
