I don't mind the big ferris wheels where you are enclosed in a gondola, but the old ones like KI had years ago sacre me. I don't like the fact that if someone stupid rocks their seat hard enough, they could flip it over and while falling, knock you out of your own seat. I saw this happen once and it was horrible. The guy who caused the whole thing was the only one who didn't die or get hurt.
I would love for PKI to get one the big ones that I mentioned first. That would be nice.
