Context: Leap-The-Dips is a wooden roller coaster located at Lakemont Park in Altoona, Pennsylvania.  Constructed in 1902 by the Federal Construction Company and designed by E. Joy Morris, it is the oldest operating roller coaster in the world and believed to be the last surviving side friction roller coaster of the figure-eight variety.  Leap-the-Dips operated continuously until 1985, when it closed after falling into disrepair.  A fund-raising campaign led to its restoration, with refurbishment efforts beginning in 1997 and ending with a grand-reopening in 1999.  It was designated a National Historic Landmark in 1996 and received the Coaster Classic and Coaster Landmark awards from American Coaster Enthusiasts. Fujiyama is a steel roller coaster at Fuji-Q Highland, Fujiyoshida, Yamanashi, Japan.  When Fujiyama opened in 1996 it was the world's tallest roller coaster at 259 ft , and had the largest drop in the world at 230 ft .  Fujiyama was also the world's fastest roller coaster for a year of its operation, succeeded by Tower of Terror at Dreamworld theme park in Queensland, Australia in 1997.  Despite being the world's fastest roller coaster in operation for a year, Fujiyama set no world records for roller coaster speed.  Steel Phantom at Kennywood set the world record for speed before engineers added additional brakes to slow the ride down because of safety and rider comfort concerns. The Wild Cat (initially The Joy Ride) was a wooden roller coaster located at Hersheypark in Hershey, Pennsylvania, United States.  The roller coaster was constructed in 1923 by the Philadelphia Toboggan Company (PTC).

The roller coaster operated from June 16, 1923, through September 1945.  PTC and Hershey Park elected to close The Wild Cat and construct a new roller coaster in 1946.
