Shelter comes first. This page includes resources for the building of both long and short-term shelters. It's a skill you learn so much by just doing it. It doesn't take many nights of being cold or wet to learn, not only how important the skill is, but how to make yours more effective. There's also nothing quite as wonderful as living in a shelter you have built yourself... and nothing quite as sad as returning a shelter to the Earth that has protected you and created a sense of home.
