Forget about being well fed in sub freezing temps. Not going to happen.

Cultures that have endured such conditions have prepared for it during warmer, greener months.

In really cold weather your priorities are shelther, warmth and rescue or getting to greener and warmer pastures. Sure, one can fish through the ice, but only on a really good day is this worth the energy expenditure.

Sure, one can shoot a large game animal, but don't count on them standing in line waiting to be shot just so you don't go to bed hungry.

Have your stash ready or expend your energy moving on.

No pun intended, but that is the cold, harsh reality from a Wisconsinite currently living in single digit temps. It is simply unsurvivable without a stash of preparedness.
