I've ridden two roller coasters in my entire life. That's enough for me.

The first: During a trip to San Fransisco with my girl scout troop. I don't remember much of it, I only remember riding a roller coaster there and it scaring the piss out of me.

The second: In 8th grade, on a field trip to Silver Dollar City. I think it was called "The Powderkeg." I absolutely hated it.

Firstly, because I had to remove my glasses. I can't see without my glasses. I am literally only a few points away from being considered legally blind without my glasses...so I couldn't see what was happening, or where I was going.

Secondly, because I was riding it with a girl I barely knew, who took pity on me and decided to ride it with me.

Thirdly, because I spent the entire ride screaming at the top of my lungs and cussing out of sheer terror.

Twice is enough for me.
