Every trip, I say I'll go on Tower of Terror, but can never bring myself to do it - but not entirely for the reason most people think. Back when I was in high school, my summer job was at the local Six Flags park. They had a drop ride that was basically the ride up, a slight move forward, and a free fall drop. I had no problems with the ride (and even rode it multiple times on the employee preview night). However that ride had an awful malfunction one morning while I was working - when the ride got to the top, instead of moving forward for the controlled drop, it crashed back down the "up" shaft. I was working at the entrance area of the park, and the ride was 2 areas away - but everyone heard the crash. I know ride technology in the following 35+ years has improved tremendously, but I can't bring myself to ride. So my 86-year told dad goes on by himself, and my mom and I have a snack and people watch while we wait for him.
