Do you have a copy of the road guide to South Dakota hauntings? Not that I am trying to plug their book but it does have a lot of sites in the Blackhills. Laurie and I are busy gathering ghost stories from around the Blackhills for our own research. We thought this might be difficult but seems to be easier than we thought. I'll let you know if we find anything around Keystone; right now we are mainly hunting around Lead. Plenty of stuff around Lead.
Lead is the town with the Homestake goldmine; fact is the name of the town is a direct reference to the discovery of the same goldmine. I believe there is a KOA near Custer but Laurie and I usually stay in Deadwood. We plan to retire there in a few years so we spend a lot of time in that area. We keep a blog about this and will be posting a lot of our stuff probably early next year.

There are lots of haunted places in the Black Hills. I live in Rapid City and just did a reading at the Prairie Edge Museum and store in downtown Rapid City. Lead and Deadwood have lots of history including the Bullock Hotel, which has a few very interesting spirits hanging around in there. If you decide to get a room there, ask the clerk for one of the haunted ones. The old Keystone Cemetary also is a neat place to visit, it has a great view of Mt. Rushmore and many of the workers that once worked on carving this mountain like to come out and view their work. I can name more, but there are tons. :-)
