In ND, most of the time it’s safer to stay in a running truck than to get out In the cold to try to find help. I always thought that if I slid off the road, I might not be found for a week….
This time sounds like the exception, since there was contact made with civilization, and police apparently offered him shelter.
One time I spent 3 1/2 days stuck in my truck, at a gas station because Wyoming closed the Hiway. Town of Rock River, Wyoming- population 264. No other businesses there but the gas station and a taxidermist next door.
