Nobody is saying that bison can’t put up with bad weather. They were historically found all the way to the shores of the Arctic Ocean. But we aren’t talking about cold, we’re talking about snow. You can go around a drift, and despite what you seem to think, bison migrate to locations where forage and grazing is better; animals that can’t migrate (for whatever reason), or can’t adapt, die. Sounds like you just want to argue...
