After 14 years in operation, the landmark Corkscrew rollercoaster closed to the public on September 17, 1989, to make way for Boomerang. The Corkscrew was the absolute first of its kind, a $1 million, prototype upside-down rollercoaster that Marion Knott purchased from Arrow Development and debuted with great fanfare in the new Roaring 20's in 1975. Over the years, 31 million riders flipped for Knott's Corkscrew before it was sold to the Silverwood amusement park in Idaho.
