For those of you who speculate it would not be practical, let me give a live example. I live in a wooded area with only a few exits out. When I got evaced for a fire 2 of 3 routes out were closed. We managed to get out of town and to a primitive site in a safe area. Hotels were full. I had my camper for a couple of days vs sleeping in a school makeshift shelter. Is that good enough?
Plus, one could go to a Wally or other parking lot away from the burn and stay.
I totally understand those of you that would be in a major traffic jam.Of course it wouldnt be practical. You can shoot it down all you want, but until you lived in my world, dont knock it!!
