On the PKI website, PKI is listed as the manufacturer of the Son of Beast. The local paper in Springfield (OH) said that PKI was going to sue the supplier of the lumber used to build the ride and the designer of the ride. They didn't use Werner Stengel by name, but it is widely known that he was the one that designed it. Since I'm about 60 miles NE of Kings Mills Ohio, the article that ran in my paper that day back in 2000 was probably from the A.P. news wire.
