I once deer hunted and it was -32 below zero but I just could not last out side. Even in a blind out of the wind. After a short time, I just sat there and started to shiver. When we ice fish we sit in huts with heaters most the time. Although there are some that will bucket sit.

Actually in this kind of weather if there is no wind, this is the time to cut firewood and expecially split firewood. You stay warm working, and the wood just pops apart when it is this cold.
