Some of the best loved attractions of Disneyland are the mountains, Space, Splash, Big Thunder, and Matterhorn. But DCA has no mountains despite the fact that California is a very mountainous state. I know that an open mountain would expose guests to the outside world, but an enclosed mountain would give DCA another E ticket while providing another visual icon for the park. Building UP would also better use its limited land.
I am not thinking of a cloned ride from some other park, but a totally unique ride that would give DCA a signature experience.
What do you think?
What theme would you use?
