This is an incredibly odd situation. I went to Six Flags New England on the 20th with my father and little brother. My little brother is right on the 54-inch mark, and I doubted the possibility of him getting on Bizarro. They measured him and said he was good to go, both at the entrance and in the station. If my little brother can get on those rides, why can't KidTums? Must be a Great America thing.
