I have had one, once... but it was the scariest! It was at Kennywood (where I have never been.) I got on B&M's original prototype for a speedcoaster. After the 250 foot lift, it had some 20-30 foot drops high in the air, then, the big drop... It had massive negative Gs. It felt like -3 to -4Gs in my dream. I then got sick and almost barfed! That would suck! Afterwards, I rode Steel Phantom, and at the time, Phantom's Revenge was being built IRL. Strange, riding a coaster that no longer exists.

Hey, SFGAm management, can I buy a couple cages of Sky Whirl?
