My husband insists that I carry my bug out bag in my vehicle when I travel for work in the event that I have car trouble. Thanks to him, I could be dressed in arctic winter gear, have a windbreak set up, a fire burning, and be drinking a hot cup of coffee in a short amount of time. It may seem like overkill at times, and some people may think I was nuts if they saw what was in my car trunk, but if I ever have car trouble I will be okay.
Chances are you won’t need it but when you do....
I used to hike a bit and I always carried ample supplies. It was more weight but the couple of times I needed it turned the hike from a miserable experience to a very pleasant one.
