No, I'm not talking about the dismal attendance numbers for Disneyland's neighboring park since it opened, nor am I measuring its creative success or failure.
Once upon a time, Disney's California Adventure had a shoot-the-chutes attraction on its roster: Wipeout. This ride in Paradise Pier never materialized. In fact, with the earliest initial plans of the Imagineers, this area wasn't even known as Paradise Pier but rather, Surf City. While not exactly Splash Mountain, the attraction would have added a bit of action on the bay, becoming another must-do winner to a section filled with spinners and ordinary carnival fare.
