I've never been a huge fan of roller coasters. My sister used to take me to Worlds of Fun when I was a kid. We'd ride this enormous green monstrosity called the Zambezi Zinger. It had twists and turns and climbs and descents (I don't know the roller coaster aficionado vocabulary, so I'm making it up as I go along). The two things it did not have, however, were loops and a reputation for trouble...
