The Zippin Pippin, formerly called the Pippin, is one of the oldest existing wooden roller coasters in the United States. It was initially constructed in the former East End Park in Memphis, Tennessee in 1912 by John A. Miller and Harry C. Baker of National Amusement Devices. The construction material was pine wood. As the park declined in popularity, the coaster was dismantled and relocated adjacent to the horse track in Montgomery Park, now known as the Mid-South Fairgrounds. Purchased by the city of Green Bay, Wisconsin in 2010, it was installed at the Bay Beach Amusement Park, where it is once again in operation.
