National Lampoon’s Vacation “We watch his program, we buy his toys, we go to his movies…HE OWES US!” The Griswold’s make it to Walley World only to find it’s closed for repairs for two weeks. The moose told them and Clark did not like it, so he punched him in the nose. While everyone knows that Six Flags Magic Mountain is the park they used for Walley World, the entrance was the ticket booths at Santa Anita Park, the Thoroughbred racetrack in Arcadia, CA. The parking lot scenes were done there too. This particular scene was filmed at the south entrance. Wider angle shot in the comments. Santa Anita Park 285 W Huntington Dr, Arcadia, CA
