The Aftershock and Alienator concepts looked awesome, I love the whole "destroyed city" thing! When I saw that the Brady Bunch was a considered theme for this ride, I couldn't stop laughing, epically at that name!
If I saw a or heard of a roller coaster called "Groovy Train", I would automatically think its lame. For the ride its self, it looked kind of boring to me, its drop, hill, turnaround, hill, hill, turnaround, brakes. The elevator lift would of been cool, but unless there some great airtime or laterals, I think it would just be a short version of Wildthing, fun, but not the awesome ride you think it would be.
