I totally get the sleep in car, or snow cave. Hotels are damned expensive when all you want is to rest. I used to sleep in my car by putting down the back seat and stickking my feet in the trunk under quilts, I could afford the hotel but didn't want to waste the cash on esentially a matress. This was traveling in Oklahoma in the. Winter by myself. My mom went ape too. Park under a light and crack a window and I was set. The. Trick is to stop liquids 4 hours before.
