Since we are dealing with heart-warming anecdotes, let me tell you about my disability: I can't climb Everest. But if somebody were to put an escalator up there, I sure would appreciate the view.
Problem is, on a day when 3rd graders died in their school because there was no tornado shelter, I feel the obnoxious thing is to talk about someone's ability to use a purely leisure tram at 8500 feet... save for the elevator that puts him there "unassisted". Besides, if once in a blue moon a handicapped person did want to take the tram, me or anyone else there would help carry him up the 8-10 steps.
And the hidden cost of laws like this and the lawsuits that accompany them is that a lot of opportunities are unavailable to the public at large because it makes the whole enterprise a big money drain & risk. To wit, the recent controversy over contraptions to allow handicapped to enter every "public" pool&hot-tub unassisted (not the ramp to get there but being lowered into the pool). These things cost real money, and real pools will close down because not everyone can afford the extra $10K per pool/hot-tub + maintenance, plus lawsuits from children playing with, then getting tangled up in the darn thing.
