I couldn't ride a roller coaster or I could but it was more then a lot embarrassing for me to
(I felt like everyone was staring at me, plus the guy helping me was very frustrated w/me and made me feel horrible on top of it all). Then even when I was on it the ride was very uncomfortable for me to ride on, I was so so crammed in it. Another thing I have heard horror stories about is airplanes and their seats. I don't dare (after my trouble with the roller coaster seat) go on a plane ride until I loose some weight.
