Compared to where I grew up Alaska is pretty darn cold, but I've got most of the lower 48 beat. Caribou, Maine regularly records nationwide low temps, and usually the average temp during the wintertime is 0 F. We have to use block heaters in all our cars and once in a while we'd have to whip out the Silent-Glo to heat up the engines enough to start. My cousin moved to Alaska from Maine for a year once, and she came back with stories about how much colder it got there.
