A good article in the Chron about the San Francisco Bicycle Coalition's Urban Cycling Workshops, which teaches cyclists how to ride more safely in San Francisco.
Linda Atkins, an everyday bike commuter who hasn't owned a car for 20 years, was amazed at the difference in perception a little training could make. "It was like night and day," she says of her experience with the Urban Cycling Workshops. "I felt much safer, much more relaxed, much more confident."
Fritz - since you have the cert can you do a longer post on it? I've never really felt the need to do the class and have ridden some pretty hairy cities (Oakland, Baltimore) without feeling that what I was doing remotely approached 'death defying'. I would love to see a discussion of the value-added from the course though.
