Continuing this stream of mammals of the Mountainous West, here are some Bighorn Sheep. So named because of their, well...
I am convinced that, like deer, the only purpose they seem to serve is to be mountain lion and soon-to-be newly, reintroduced wolf food. They're nasty effers who will knock you off a hiking trail, piss on your stuff and then stand in the road completely ignoring any attempts to shoo them away.
Plus, for sheep living at the frostline their coat game is not on point.
