Rivers of America 1966

This picture was taken in 1966 which was three years before the Haunted Mansion was finally opened.  Can you imagine going to the Park year after year and seeing this building but never being able to go inside or know what was inside?
You can also see one of the Keel Boats that used to go around the river.
