Twisted Nightmare, L.L.C. is a haunted house that is brought to you by the talent of your local Fraternal Order of Police. It is through the talents of our membership that we present a view into the haunted world of Sioux Falls. The haunted attraction is a fundraiser for the FOP and a local food bank. A fun time for all. We are located in the future home of Raceway Indoor Sports Entertainment Center to the North of Burnside Street and N West Ave. It is directly North of Burnside Park. Enter from the South side of the building. Off Street parking is available with additional parking available on side streets.
