I've never been lost, but came close to having to spend the night in the mountains while elk hunting . I just ended up getting further away from camp than I had planned and was not going to make it back before dark. I was close to two miles away, and was in the process of finding a place to set up for the night. Needless to say my hunting partners fired shots every 10 min and guided me into camp. I knew right where I was, but wasn't about to try to find it in dark. I always carry fire building supplies and space blanket etc.. When hunting just incase.
