The CloudFest Hackathon took place inside Europa Park, an amusement park themed after various European cultures. On one of the nights we were granted exclusive access to the park, after hours, and were specifically given access to the roller coaster in the video. At first I rode it twice with a friend, but he and the others in our pod were done after two runs.
After a bit of good chatter I decided that I wanted to go back and ride it again before I missed the opportunity. After that third ride, however, I discovered that the queue was empty and I could stay on the ride for another round. Because it was so good, I stayed on for four consecutive runs. Two of them were through some rain that was heavy enough to hurt a bit.
