Snowshoes so you can navigate around that motel parking lot you're going to stay at. If you're hell bound for leather and must do it, here's some tips. Having done winter exercises, some in extreme cold, make sure you have a good quality air mat and cot to get off the ground. Never climb into your sack with clothes on, you'll sweat then get cold and freeze. Hang your clothes to dry, they may be cold as a witch to get into the next morning, but dry. Would I do it again, nope, been there, done that at at -52.
