Nice article on Willowhavenoutdoor about what we should keep in our vehicles at all times. I think most folks have their 72 hour kits by now and a lot of folks have a bug out and a get home bag but when you think about it if you are bugging out or trying to get home in an emergency situation you will probably be depending on your vehicle to get you where you need to go. The items on this list will help to make sure you do get there.
