We are planning on spending one day at IOA and wondered if the park has limits on riding rides with a cast over the wrist to halfway between the wrist and elbow. Will he, my son, be able to ride the Hulk, dueling dragons, spiderman, ripsaw falls. His doctor gave the OK as long as he doesn't use that hand to hold on (he is one of those that puts the arms up anyway, no big deal to him). Thanks for the inputs. Great Boards.
