I've hunted Wyoming for pronghorns many times, including last year. It has probably three times as many pronghorns as Montana (according to estimates), and perhaps as many as the rest of North America put together. It is the center of the pronghorn universe.

Wyoming also has quite a bit of public land, plus some places were landowners aren't averse to allowing hunters to reduce their goat population.

Lately the only problem down there is a LOTS of oil and gas development, which in some areas does seem to affect pronghorns, though in other areas it doesn't.
