On Monday, June 21, the first full day of the thirty-third annual convention known as Coaster Con, two of Kennywood's oldest wood coasters were presented with Landmark Plaques. The Racer and Jack Rabbit were both honored for their historic significance. It is the first time in the club's history that two Landmark Plaques were unveiled in the same park on the same day. Racer is the oldest racing roller coaster in the world, and one of only three racing coasters in existence with a single-track design. The 1920s Jack Rabbit is well-known for its 70-foot double dip into a natural ravine. Both coasters have been in continuous operation for over 80 years and both were designed by the legendary John Miller.
In addition to having two coasters honored, Kennywood earned the distinction of being the first park to host the ACE convention four times.
