Went to San Francisco yesterday intending to climb more of the steepest streets, but when I got there I took one look at 22nd Street and said F-it! I wanted to climb, but I didn't feel up to maximum effort up 31.5% grades, or the cobbled 30% grade of 24th St on Potrero Hill. The fact that I got there hours later than I wanted didn't help. The queasiness I experienced near the top of Sanchez St finalized my decision to avoid The City's steepest.
Instead I rode around the Noe Valley and Diamond Heights areas. There are plenty of grades in the mid teens to low twenties, so that was good enough for me. Where else but San Francisco can you ride less than 11 miles and climb over 2,000'?

GoPro and Contour really need to work on their cameras to make them more usable at night. Even on well-lit streets, all the footage recorded at night was useless. This sucks because I climbed the steepest hills after dark.
Here's the footage that did turn out okay. These hills only have grades in the mid teens to maybe 20%.

The hill I didn't climb-22nd St

Crappy evening shot of Sutro Tower from the top of Cumberland St
Even crappier night shot looking up 21st St. I had to stabilize the camera on my saddle, so excuse the angle.
