I can ride almost any thrill ride, but I hate Ferris wheels(I don't get sick or anything, I just always get this trapped in a cage/chair of death feeling).
DW happens to love Ferris wheels, so we tried both the swinging, then the non-swinging. She mustered up the courage to ride a looping coaster(California Screamin') with me(she hates loops) so I went along with it.
Of course, I hated both. She really hated the swinging ones but also felt really uncomfortable in the non-swinging ones.
