Another time a friend and I were back country off trail snowmobiling with the intention to winter camp in the woods overnight.  It was about -25 without wind-chill. After a few hrs of making trail we decided to hightail it back to a heated cabin.  Needless to say I'm accustomed to outdoor cold weather activities unless I work up a heavy sweat dangerous misery soon follows in my experience.
