I like that idea.
They could make it look like you are diving through a Roadrunner and Wile-e coyote style canion.
Or even better: make it look like a bunch of 2002 Corollas are parked beneath as you ride by!
^ I always thought that maybe they should hire a 'street artist' or some painting company, to create a 3-D painting, underneath that coaster. It could be quite something. And be able to be refreshed when needed.
