I'm an architect living in Berkeley, California with my wife, mother, and two sons. For the past 12 years, I've led dozens of bike tours as a volunteer for the San Francisco Bicycle Coalition. Last year, for the San Francisco Chapter of the American Institute of Architects, I lead an amusement park history tour of San Francisco. The tour was great fun, and all of the tour participants had a great time. I'm hoping this years tour on the theme of "Hidden San Francisco" will be equally Successful, and I hope you enjoy this tour.
