… When I read that Montana is down to minus 50 I do wonder how farm animals survive and does antifreeze work,I suppose people are used to low temperatures but minus 50 must be really exceptional.
They have some very large barns they put the cattle in and feed them on hay and feed. Others have a snow fence built facing the prevailing wind. The snow piles up along the fence forming a snow drift and the animals shelter in the lee of it and keep warm out of the wind. Wind chill factors can easily be 90 below zero.
It regularly got to 30 below when I lived there, and one winter got down to 40 below, which had even the locals a bit worried. We had to move a horse in our back paddock to a sheltered area in the lee of a shed so it could get out of the wind and it was OK. Also had to keep plenty of feed up to it so it could generate its own warmth I guess they grow a thick winter coat living in that climate.
Antifreeze in vehicles seemed OK at those temps as long as it was not old or too diluted. Plug in electric heaters are used to keep engines warm overnight by some. I did not bother as my car started well in the cold. Did have cardboard down the front of the radiator to stop it freezing up while driving though. At 40 below, the car's tyres had flat spots frozen into them from standing overnight so it was a bumpy ride the first half mile or so until they warmed up and popped out round again!
Rule of thumb was if driving out of town in that weather (yes they are crazy enough to do that) is to carry a heavy duty sleeping bag, matches, candles and a large plastic bottle to pee in . So if you break down or get stuck in a snow drift, you can keep warm, and don't have to open the doors to get out to pee. You just have to be careful not to burn up all the oxygen in the car if buried in a snow drift, or running the engine and fill the cab with carbon monoxide.
Its a whole different way of life. The area was settled by Scandinavian immigrants who thought it was just great, just like home!
