Yes I have. Last I was there, the population on the west side, from the Spearfish ish area north to the border, and west of the river, was very good. No different than any other public antelope hunting. Size was more MT like than WY like. The one caviot is there was a very bad die off in much of SD a few years back. No idea if it has recovered or not. There maybe some members in the area who can give you a better idea of things. Find fairly open public land with water...hunt away. Have not been out there for 3 seasons, but hunted SD regularly the 12 prior years in the general area I mentioned.
