Flooded mine, Fire in the Hole and the train should be able to accomodate your husband. The tightest fit, so to speak, would be Fire in the Hole, they have to put down a safety bar that might be a bit tight, depending on how big a fella he is. The park is located in the Ozark Mountains, and is mostly hilly, but the main street area, grand exposition, and riverfront areas are fairly level. Take your time, sit down on a bench and people watch when you get tired, and enjoy your day at SDC!
