A deal has been met between SFI and the Kentucky fair board. in that deal SFI will keep Road runner Express, a mine train themed wild Mouse. I have come across a few theories that have it coming to TGe.
The mine train fits with ghost town and the empty Nightmare building. Also TGe is pretty much the only park in teh chain without a coaster of it's level.
Well the coaster went to SFNE instead. no one is thrilled over it.
The mouse may have been a last ditch effort to add a coaster since they were unable to add a Euro fighter since another local park, Canobie LAke , beet then to the punch.
