I have been a bit twisted up direction-wise in the woods, but never had to face an unplanned night out with the elements. What would you do if you find yourself hours away from getting out of the woods and you're a hour away from dark? You sort of know your way out, maybe not efficiently, but you don't have time and you don't want to be wandering around in unfamiliar woods with a flash light. I would stop, and settle down a bit as I would already be feeling a bit unzipped. Inventory the stuff I have with me, search for fire wood and assemble and prepare for a chilly night with mother nature.
