They need to remove Rt 66 and make the area San Fransisco. Or they they can do this in the place where the Incredibles ride is set to be. Id love to see a water coaster like they have at seaworld, but with an Alcatraz theme. Imagine the showroom in the center of an enlarged lagoon, the waves crashing against the rocky base of the forboding prison.
And as for a Gold Rush expansion, I would like it to be in the forested area but the genious at Disney decided to build a giant hotel inside a park that was already too small to begin with.
