Robsev, sorry I'm kinda late to this conversation and you may have already contacted the game and fish. But this tag was put together for a couple ranches near hyattville and ten sleep, the alm ranch (formerly known as the hyatt ranch) and the mills ranch. The herds bounce back and forth from private to public and will probably take some time and effort to catch them on the public, I'm not sure if the either ranch will work with a guy for a cow or not. The game warden for 45 told me this summer that the alm ranch said they would allow some cow hunters if they came out with this 45-6 tag whether they are staying true to what they said I'm not sure. Your best bet would be to contact Matt Lynch (game warden for area 45) he will give you the ranch names and all the specifics. As far as terrain it will be pretty easy hunting at the foothills near the irrigated land, maybe a few cedars, lots of sage brush, some hills and ridges but nothing rugged.
