I lived there on and off throughout my childhood. It blows for the most part. Sioux Falls the city the UFC is in tonight is alright though and probably the only somewhat cool place in the entire state. I lived all the way across the state from that city though.
I lived in Rapid City. It's a small ass city in South Dakota that has somehow managed to be ghetto as fuck and have gang problems and at one point was considered the rape capital of America per capita for years lol
The first time I saw Tool in concert in 2002 and when I saw OG Guns N Roses in concert in 1993 was in Rapid City, so that was cool. Probably the only good memories I have from that state lol
