I have hunted alot not far from Cheyenne ....always saw limitless bucks....always got a good one. I drove around and just asked a landowner.....always very politely...always with a promise to never leave a gate open or trash anywhere....and ALWAYS talked so fast to get said all I needed to say to be convincing, before the landowner could say "no". I LOVE WYOMING!!!......now live (gag) in Florida. The biggest bucks I have ever seen were between Baroil (north of Rawlins) and Crooke's Crossing. The worst road I have ever driven in my life was between Baroil and Crooke's crossing. That region is untreed, rolling hills.....approaches would be murder.....maybe that explains my finding "reach-out" spent cartridges like the 240 and 257 Weatherby there. But, I envy your going to WY. If you're near Cheyenne......try the "Little Bear Inn" for great steaks. Whoops...just remembered.....huge bucks north of Green River also.
BTW, about 40 miles west of Rawlins on I-80 is an exit named "Booster Road". At the base of the exit is a small, red-bricked building which contains (I assume) the machinery to "boost" pressure in a pipeline running E-W beneath. Immediately to the south is a ridge ...maybe 50 feet high....on the other side of that ridge (near the top) I found many many stone tools, including "oolite" hand axes. Also....beautiful selenite "roses" ....large and gorgeous crystals of selenite. I also found a petroglyph there...of sandstone .... tried to get the anthropology dept. of Univ. Wyo. interested, but I guess they are overloaded with ancient sites, and rejected my information.
