The fire thread made me realize that I've never seen that much mentioned about survival shelter. So I was just curios as to what some different thoughts were on the best wilderness shelters? As a kid I could put together a lean to (sp?) really quick using a large bent over sapling in a strategic location. I would then add more saplings to it to close off one end and then weave in branches. It wasn't much but it would keep the rain off on a cold day. So what are some other options, besides a tent?
