“Dirk Auer, a 36-year old dare devil, roller skated down a roller coaster. He created 16-wheeled inline skates that fit on the rails and helped him to reach top speeds of 56mph. He made it through the 2,822 foot Mammoth coaster in Stuttgart, Germany in just over a minute. Congratulations?” (via A Real Roller Coaster | Offbeat Earth)
