Courage Tester

I am a rollercoaster enthusiast. I enjoy a good thrill ride (though I very rarely get the chance.) But today I may have found my match. The world's tallest and fastest coaster is at a six flags in Florida. It's called "Kingda Ka", but I think "You Must Be Crazy" would be more fitting. This thing is 45 stories tall, and uses a hydraulic launching system to power the car up and over the massive tower of steel. Read a description of it here.
Then, for even more fun, go on a virtual ride here. Someone made a video somehow while they rode this coaster. I don't know how that is possible without dropping the camera. It's very well done, and breath-taking.
So the question is: If I were standing in front of the Kingda Ka this very moment, would I ride it or chicken out? I'd ride it. But, I would be extremely nervous.
