Why would anyone suggest removing the only real draw for Frontierland? This is a land that desperately needs expanding and I would love to see how Disney can expand on the wild west/frontier expansion theme.
If they had to put a ride in like the dwarf ride at Disney World, let them put it in the theater. There is plenty of real estate there. I would prefer that it be themed to something other than Snow White though, as that movie is already represented.
