I've been before, it's a pretty unique looking place if so.
I suppose technically it could also be North Dakotas badlands, which are greener, yet cooler than SDs.
That is, if the title doesn't have some other meaning.
Still, seeing people yeeted off of the plateaus and buttes of SD could be interesting. The badlands just kind of are there in the middle of the plains. You just drive down a hill and then bam, they appear.
