In a related story that might tick off some of the hardcore, I've decided I'm for re purposing Test Track into
Mythbusters Test Track. Basically retheme the attraction into dedicated to using science and technical know-how to see science in action, or inaction depending on the myth. Keep the layout, axe the GM thing, fill the queue with special effects replicating some of the myths, add much needed science and smart thinking values into the attraction, while punching up the fast paced ride with explosives and familar personalities. Then an entire post show where you get to get hands on with actual rumors and myths, cycling out as part of a more involved and active post show experience.
Plus all the cool Fire, Smoke, Liqud Oxygen, crashing, exploding, water, light, and darkness effects.
And Jamie, Adam, Tori, Grant, and Kari would be great hosts, lots of comedy and science there.
