Are there any rides out there (that you've been on) that have made you feel like you were going to fall out or the ride was going to fall apart at any minute?
I only have one that I can think of at the moment and that was Snake in the Grass at Pleasurewood hills. I've been on plenty of that exact type of ride before and after that one but just one corner of Snake in the Grass made me feel like I was going to fall out. It was a rather steeply banked corner and I was in a cramped seat without much grip and a bar that came no-where near me was all that was holding me in. The vibrations from the train didn't help and it did feel like I was about to fall.
I have no idea why it was just that one corner on that ride. I felt it every time I went on the ride and yet always feel perfectly safe on every other ride, including ones of exactly the same type.
