Three car camping in a snowy parking lot tales:
In my new car at Crystal Mtn. WA, woken up at 6:30 AM by the sound of the snow thrower starting up and chewing into a snow bank. Followed soon after by the sound of a torrential downpour of slush, mud and rocks on top of my new car.
Mtn. High/Snow Summit CA (can't remember which one), waking up every so often to move my car back to the high end of the lot. Freezing rain had made the lot a skating rink and high winds kept pushing my car downhill towards the drop off with no guard rail.
Timberline, OR, about 3AM in a snow storm, the back end of my car lifts off the ground. I get out to a startled tow truck driver who says I'm parked illegally. he unhooks and takes off. I check with management the next day to find that I was parked legally and the tow truck driver was probably just trying to steal my car.
I stay in hotels now.
