I'm probably a novice compared to most people, only having ridden 15 coasters or so, but i don't really get scared anymore. I think the thing that did it for me was riding Dueling Dragons in the front seat, having been dragged on by my brother. I had been on Kumba, Sheikra and Hulk before that, but i was horribly scared on Dueling Dragons. In the line my hands were shaking and my heart was racing. But once the first drop happened, I was fine, and now i can't wait to ride another one.
