I have had very good luck straight west of Pierre. The ranchers are usually more than welcoming to PD hunters out there. Randy is correct, the ranchers talk to the CO’s, so if you give them a call, they will tell you which WIA’s are hot right now. About 5 years ago, we ran into a rancher on one of his access roads while we were shooting PD’s on his WIA and I thought he was going to get out and hug all three of us. Very welcoming folk out there if you are respectful.
