I watched once as three attendants pushed down on the harness of a man to get him in and just thought how uncomfortable he must be. No one paid much attention, honestly, but my heart ached for him.
At King's Island there's a ride called "Demon Drop", or "Drop Zone" I think it's been renamed. My husband is 6' tall and about 225...not a huge guy, I don't think. But he has a curved back from some disk compressions. He was too big on top up where the harness narrows. I figured the assistants could help him get into it. I should have expected what happened. She came by and shoved that harness down and I swear I heard every bone in his spine crack...but by golly he was in. She realized what she had done right after she did it and just stared at him in horror. He rode it, but can probably never ride it again. I felt like the harness was kind of small for anyone so tall. My own shoulders didn't come up nearly far enough to be a problem, but for anyone who sits taller...
