Seen everything? Try this 17-second flash. The concept seems simple enough: forward, up, down, forward. There are no helixes, no inversions, and no tunnels, but it's not a relaxing ride. Riders zoom from zero to 120 miles per hour before climbing a 420-foot hill. And that hill is steep — a 90-degree angle in both directions. The Dragster is perfect for anyone who is not faint of heart or long on judgment.
