Giant canyon swing always gets me. Obvi it has the positives and floater like any s&s swing, but the acrophobia of feeling like youre about to be hurled off a cliff, combined with the amazing scenery makes it such a top notch installation for me.
Knoebels is actually working on adding a Rock-o-Plane as well..... I'm so looking forward to that. I really would love to see them add a Zipper as well.
The real win would be if they could find a Chance Turbo (only 20ish were ever made)..... That's one of two rides that I would do nearly anything to be able to ride..... The other one is a Huss Booster but only 3 of those were ever made.
