Yeah, I had someone at work try to tell me cows just move. Uh, hun, I've physically pushed them with my 1400lb hulk of a horse. They don't always move, and they aren't entirely predictable. During calving season I've had calves run under my horse! Working cattle on a big boy ain't always easy, but boy can he hold um for you on a rope.
Grey Butte near my old house still has grazing permits. They liked to congregate at the bottom of a big, fast, gravelly hill. That made life interesting. I almost gave several knobby tired enemas to cows who changed direction and got in front of me. Good times, good times.
