We were there this past Sunday as well (8/24). That had to be the busiest day at Dorney I have seen this season. We arrived early and the parking lot was filling fast. By noon, the park felt packed. Unfortunately Steel Force broke down around 10ish and was down for over an hour. I really hope they thoroughly clean or replace the restraints on Hydra for next season. They are turning black and the B.O. smell is nasty.
Talon still is, IMO, the best coaster in that park. At least I got to ride that one 3 times.
As for a new ride, it's not looking like there will be anything for 2015 which is really disappointing. Snake Pit wasn't anything exciting for me, we did the water park 2 times this Summer, the lines are just too long to enjoy it even during the week. I guess that is the downfall of one ticket, two parks. They can get away with considering a water slide a new ride.
Some mentioned they could use the area where they do the Grave Walk for the new coaster site, but considering Grave Walk is being set up there (I could see the graves) this is unlikely. Dino's Alive is still very much alive minus the crowd. There seems no evidence of that coming down at the end of this season. Also, the parking lot has no markings that I could see. So, it looks as though Cedar's stepchild won't be getting anything exciting for next year. Looks like, now, 2016 will be Dorney's year for a new coaster.
