Weak stomachs, not welcome.
That's the warning about a new ride – titled "The Joker" -- slated to be unveiled at Vallejo-based Six Flags Discovery Kingdom in 2016.
Officials say this is the first roller coaster on the West Coast that features a "breaking-wave turn," which means riders will be rolled, flipped and turned upside down.
"The Joker” will be ready for use next spring.
