Lived on the eastern side of the state most of the time. Actually grew up in a small town within an hour of Sioux Falls (which is where I currently live). Did spend about 4 years living in Pierre, which is in the center of the state but only a little over 2 hours from the black hills, so I've spent a lot of time out there as well...

I actually have an aunt & uncle that live in Gillette, so I'm a little familar with the area. Though it's been a few years since I've been out that way...
