I was just going through a box of my old Boy Scout stuff and found an old wilderness survial merit badge book. As I was flipping through it I recalled the six things repeated during the course:

Shelter
Fire
Rest
Water
Signal
Food

I was thinking that I have used this list in order, while in military schools and civilian practice (fun when the wife let's me go out in the woods with friends). If you look at the time it takes for someone to be found this in my opinion is pretty good. Just wanted to see other ideas....
