People don’t normally live outside in northern winters, but they could. Lots of animals do - squirrels, beaver, deer, coyotes, and chickadees. They eat whatever they can find and they sleep in trees, holes in trees, and dens. People who live outside mostly sleep in tents and bring food that they bring from home. No matter what you eat or what you do outside, when you pitch a tent in the snow, it’s always an adventure.
