I think behind The Dark Knight Coaster because there is alot of space over there and the can use the Old Country site also. They can also add some rides by where Time Warp was. That path is really creepy when I walked passed there. They can build some rides over there.
I agree. They could put some flats like a Zamperla Hawk 48 model in the coming years. I have seen these rides poping up more and more latley and if SFGAdv gets one the whole Six Flags chain may have one(Not including Discovery Kingdom they already have one). The GCI woodie may be good. It could have the Evel Knievel theme like Six Flags St. Louis does. It would be even better if it would be built by the Gravity Group. That would make Great Adventure that much better. It should be like Voyage and Hades. That would be pretty awesome!
It would look like Top Thrill Dragster's que line at Cedar Point. But they may not do that because of safety reasons as someone said before but it would be cool to see that happen.
There is Demon Drop at Dorney Park. Flying Falcon at Hershey Park and Condor at Morey's Piers and SFGAm. There is Beserker at Kings Dominion, Southern Star at Carowinds and Looping Starship at Valleyfair. There are lots more that I don't know of.
