Well, regardless of breed sentiment like minded groups it you get to the Black Hills of South Dakota during the warm months rally or not you will enjoy the trip and your rides around the hills.
Lots of fine well maintained two lane twisties from Spearfish Canyon in the southern hills and all the way up to Custer state park and the Northern hills. Deadwood is a neat little town to visit (it was resurrected when gambling became legal in Sodak.) Plenty of bars and restaurants, lakes , places to camp, Mt Rushmore for those who have never seen it.....
