"Originally themed as a gypsy camp, and later re-themed to the "Roaring 20's" and "Knott's Airfield", this area is home to most of the park's major thrill rides, such as the recently constructed Xcelerator (which replaced the failed Windjammer Surf Racers, known to be a mechanical nightmare by employees), Supreme Scream, Riptide, and Perilous Plunge. Other rides include the roller coaster Boomerang. It is also home to the Sky Cabin Tower, which once also housed the Parachute Sky Jump attraction and was, at one time, the tallest structure in Orange County. Supreme Scream is now the tallest structure in Orange County, at 312 feet in height." - Wikipedia (http://en.wikipedia.org/wiki/Knott%27s_Berry_Farm#The_Boardwalk)
