I've never had a chance to hunt 84, but I hear there are some good bucks there. The private land is by far the best. The Rawlins Game Warden can likely help you get a list of places where you can line up a place to hunt. There are also a couple of good outfitters that lease some ranches in there, and I think one of them does a drop camp deal where they take some solid bucks. Some of it is open country that does not look too great, but don't over look so me of those lower, rocky draws.
Good hunting.
