This video has been making the rounds for awhile now, and every time I watch it I find myself amazed, and torn between admiration for these two skateboarders and a sense that they are insane and risking certain death, riding at high speed down a mountain road in the middle of the day, wearing nothing but powder-blue suits and carrying an HD video camera. Estimates of the speeds they reach are in the 50 to 60 mile-per-hour range. It appears to be a publicity stunt for fashion designer Adam Kimmel.
