Sparkling Joe is back again for podcast episode number 14! In this classic radio show from July 25th 1981 Joe traveled from his home in Wisconsin down to Gurnee, Illinois to go to the Marriott's (now Six Flags) Great America theme park.  There he investigated the sudden transformation of one of the park's roller coasters from a fun bumpy white coaster named Turn of the Century into a twisted looping black monstrosity called THE DEMON. Was the ride actually possessed by a real demon?! Joe brought Catholic priest Father Jerry Elstree along to help him get to the bottom of this mystery, and if necessary to perform an exorcism, and try to reclaim the Turn of the Century roller coaster from the grasp of the evil entity.
