HYDRA The Revenge

The twisted track in the foreground is the infamous "JoJo Roll" which was named after Joe Green, Dorney Park's Vice President of Maintenance and Construction.  He worked closely with Bolliger and Mabillard and since he suggested the idea of an inversion before the lift hill, he got to name it after himself!  Trains pass pretty slowly through the roll, so riders get to hang upside down longer than in typical rolls.
