In my old truck I also had a giant come a long hand winch that could drag me out of anything. I never had to use it on my vehicles, but did use it on two friend's trucks. I normally carry matches, water, some food, and a very old sleeping bag. I never thought of my power station that can jump start a car, blow up a tire, provide lights, and even plug in some items. Good post.
Now I hunt only on my property. I have a rule that on hunting days, if I don't call the family that night and miss night 2 to come looking for me. I also carry my cell phone now also, in case of emergencies.
