Folks up that way have to have block heaters in there vehicles or they go out every couple hours or so and let them run for 5-10 mins, We were at the bar at the Caribou Inn one nght while up riding for a weekend, I kept seeing people going in and outside, I figured they were going out to smoke a butt so i asked one girl and she told me we have to go out and start our vehicles every couple hours when it gets this cold, I said, OK, And i asked the bartender for another drink and carried on.................
