I say let them attempt to sue. I guess they didn't read the article about Ride of Steel last year. Yes, you are afforded certain rights as a disability, but one of those rights is not to risk your life for the sake of equal opportunity. If the park sets a guideline on what they deem safe to ride, then everyone should have to adhere to it. Not to mention every park base their restrictions off of common sense, state laws, and past accidents too. Revenge of the Mummy uses a lapbar to restrain someone. How does the person without legs get restrained? Then if they make it that you must have upper limbs too, so be it. It is their ride, not the customers and despite the denial, they are looking out for the customers safety while at the same time trying to cover their own behind. Only in the United States do you see this crap with lawsut happy people. In Europe a customer wouldn't DARE attempt to sue because the park will simply tie it up in litigation for so long that the person will go broke anyways. Not to mention you pay for everything there. No such thing as a 'free' lawyer until you win. Common sense would say this wouldn't be a winnable case there.
