So SFO 

I had a day to myself recently in San Francisco so I rented a bike and rode over the Golden Gate Bridge to the Marin Headlands. It was a gorgeous day and you could understand why people would risk grass fires, earthquakes, drought and high real estate prices to live there. If I get another chance at a day in San Francisco I'll bring my cycling kit and rent a road bike for a day long ride north of the city.

By the way, the music used in this video is “Match 104” from a James Murphy (previously of LCD Soundsystems) project done with IBM wherein they converted data from US Open tennis matches into music. You can hear more of it here.
