Pittsburgh's Dirty Dozen ride

This video is from the Dirty Dozen's Canton Ave., hill #9 of 13 (baker's dozen). It's a 37% grade, evidently the steepest paved road in the world. This year, I could only make 4 of of the hills since I had to work. I did all 13 hills the previous year, and fortunately all on my first attempt. This year, 300+ riders came out for the event which was the biggest in the history of the ride. Good stuff!
