Calling Fantasyland and Adventureland (the park's very heart) Americana is a stretch, but if you're going to call the American pop version of Tiki Culture and Futurism Americana, then you can put anything you want into DCA and find a California link. Same result, two different ways of interpreting it. The fact is that while Walt was alive, he put whatever he darn well liked into his park, be it a Swiss Mountain, a jolly old English trip to jolly old hell, or Dinosaurs on a Steam Railroad. They're there because he liked them. Disneyland is the most appropriately named park on Earth.
