I am terrified of roller coasters. This section of the thread has made me determined to overcome my fear this summer.
So I watched the video. The first thing I noticed was the Google ad running under the video for the online First Aid and CPR class - not a good start.
The video was watchable because it had to buffer quite a bit, so it wasn't all that intense. I noticed that the roller coaster track looked like a cross between a spine and those Cootie critter legs from my childhood. I watched it again in real time and I'm going to watch it again and again until I'm not afraid. Note that I won't be able to get on a real roller coaster because of a minor health issue, but maybe I can watch them on TV.
