I'm glad to help you out with that, just don't tell anybody; the locals don't like it when we give away our best secrets!
One of my favorite riding spots is the Pryor Mountain Wild Horse Range, about 1.5 hours south of Billings MT. There's just nothing like riding while a herd of wild horses runs along beside you. I've been camping before and had to jump in my Rhino to prevent being trampled after a bear spooked the herd and they ran right through my campground (when they're coming directly at you, it sounds like the earth is about to open up). You never know what you're going to see up there. You'll almost always see the herds of wild horses. But over the years I've seen bighorn rams, grizzly bears (most are unaware that they relocate rogue grizzly bears to the Crow Reservation and they often make their way out and onto the horse range), cougar, wolves, coyote, deer, elk, and just about anything else that Montana is known for. I would strongly advise against using the north entrance through the Crow Reservation as the tribe does absolutely nothing to maintain that road and it feels worse than driving cross-way over a corn field. I recommend going down to Lovell WY and coming up the south entrance. Geographically that's the long way, but you can spend hours driving across the reservation because you're limited to 5MPH due to the poor road conditions. The trails themselves are more aggressive than the section of trail pictured is. Some are challenging and very fun to ride. Here is just a small sample of the pictures I've taken over the years.
