I was thinking. What if the Rivers of America Were re routed and Tom Sawyer Island was sized down so they could add a whole new land to Disneyland and a large expansion to Frontierland. This is my idea. http://www.flickr.com/photos/31026329@N06/4088605178/
The black would be the new route of the river.
The red would be the new boundaries of Frontierland.
The Blue would be an all new land.
What are your thoughts?
