I have hunted speed goats in CO, WY and MT. I have never failed to fill a tag and have never hired a guide. An awful lot of really good pronghorn habitat is on public land and if you can use a spotting scope or binos and aren't afraid to walk a couple of miles then filling some tags is within the scope of just about everybody. Probably my favorite place to go after them is around Farson, WY. Tags are pretty easy to get, especially for does, and almost the entire area is BLM land. You can camp and hunt to your heart's content and other than opening weekend won't see many other hunters.
