I've never ridden a ferris wheel. I used to become quite literally paralyzed on the tilt-a-whirl, unable to grip the bar, completely frozen by the speed of spin.
One time I rode those swings on chains that fly you around in a suicide circle, and as soon as I got off, I threw up. In front of everyone. Mortified.
Since then I haven't ridden many amusement park rides.
Yesterday I worked Very.Hard. Not to transfer my own fears and nausea to my daughter as she experimented with rides she'd never ridden before at the local mall carnival.
