Well, I lived in interior Alaska for some time, so the question should be qualified. Guys that have lived there know what I mean. The coldest night I've seen was in 1999 and it was -62 according to the Fairbanks Fred Meyer. No phoney wind chill there, just bitter cold.

One of the coldest nights of my life spent camping was when my wife and I joined another pal and his wife for a snowmachine trip up into the White Mountains north of Fairbanks.
It was about -44 when we got to the remote, rugged cabin; the little wood stove there helped, but the real lifesaver was the bottle of Yukon Jack and deck of cards someone left there.
That -44 warmed right up when the gals decided that bourbon and strip poker was the 'warm up' trick. They were right.
