My worst fear is that I will be on a wooden roller coaster when it decides to catch on fire. I developed this fear when I was at a theme park one time. I was riding on one of those old car rides where you drive the old car around the park. I saw the legs of one of the wooden roller coasters and it had a fire extinguisher. This of course made no sense to me. I'm pretty sure that if the wooden roller coaster caught on fire, a fire extinguisher that was pretty far away wouldn't be much help. Now I will forever be afraid of wooden roller coasters.
