Six Flags Great Adventure (SFGAdv) Discussion Thread in Theme Parks, Roller Coasters, & Donkeys! Posted August 29, 2013 This looks awesome and terrifying, and I'm so glad that next year I'm finally returning to the park. As for Rolling Thunder, I'm delighted to see it go. The only coaster that I've ever absolutely hated. I've always fantasized about an Intamin similar to Maverick going in that area, but anything that replaces that pile of wood would be a massive improvement. Overall, great job Six Flags!
