The whole thing was Mary's idea: An SFBC-sponsored group ride using a route from Short Bike Rides in and around San Francisco. I proposed we ride my City Survey #4, and Mary wrote it up in the SFBC newsletter, styling it the Tourist Trap. About fifteen folks showed up.
I was late to the start, in part because I over-exerted myself producing miniature stapled 'zine copies xeroxed from the book. The idea was to give everyone the route and a sample chapter. But it was deadly hot in the window of Kinko's, and I was rushed. Riding up Nob Hill is nothing compared to the exertion of producing the 'zine under baking deadline greenhouse conditions.
The other nice people in the picture are Larry Chin and Mike Smith.
