Fished Lake John in Colorado at -27 and we camped on the lake that night. All our canned pop and beer froze and popped the ends out on the cans. But the coldest was Goldeneye in Wyoming, -32 and the wind was blowing so hard it was blowing the car over the holes. In Wyoming we don't want to know what the wind chill is or we wouldn't ever go out, cause the wind always blows and HARD. But we go out anyway, if you got the bug you can't help yourself.
