That why they make snowmobile suits. That isn't even below zero.
10 below fer a stretch might make me sit up and take notice, if the wood shed wasn't full.
I imagine these guys got pickups. You can get a fat facecord in a full-size bed.
There's probably a full cord or two, or more laying around the outbuildings - there's a heating season, even though they close for the winter.
They'll do jest fine, city.
Also, remember that snowmobile suit wearers usually go home to their centrally heated home or lodge after a day of riding.
Maybe there's that much firewood around the place, maybe not.
If you have to gather your own firewood in single digit weather wearing jeans and a flak jacket on short rations, you're going to get pretty tired of that very quickly, suburb.
Especially if you're used to living in Phoenix.
