Does Batman the Ride at Magic Mountain count? That thing could fit on my block, and that's saying something. It's super twisted and compact. But usually parks looking for small coasters don't have $16,000,000 lying around.
So without Batman, I don't really know. I've been on more Wild Mouse coasters than I can beleive...those things are death traps of whiplash!
I've never ridden a toboggan, but those are so small, that'd probably be my pick.
Enthusiasm is NOT the same as just being excited. One gets excited about going on a roller coaster. One becomes enthusiastic about creating and building a roller coaster. -Bo Bennet
