Strangest layouts in Theme Parks, Roller Coasters, & Donkeys! Posted December 29, 2013 ^^I will agree with that totally. River King Mine Train has got to be the most boring Mine train I've ever been on and didn't make sense. Question: I keep hearing that river king mine ride was a stand up at one point? Is that correct or was it replaced completely by river king mine ride?? I agree it takes up way to much space.
