I watch a lot of outdoor channels. The ones I like are the winter campers. The best part comes when the camping stubfart has the camp chores all done, and then sits down to light the camp stove. On my favourite JewTube channels the guys hardly speak at all, and just putter around with bush-crafty things.
You don’t want to be splitting wood in these temperatures. No, wood does not “warm you twice” if you have to be out in temps like this. Keep the stove blasting and keep the animals indoors too.
