Gary Kamiya riffs on San Francisco’s beauty, eccentricities, and cyclical cataclysms in this new book. First, the specs: this seven-by-seven mile square sits on a craggy peninsula on the edge of the continent and hosts seven unpredictable microclimates. It was built by the feverish Gold Rush of 1849, then survived earthquakes in 1906 and 1989, the sudden emptying of Japantown due to Executive Order 9066, the AIDS epidemic, and the silly exuberance of the dot-com boom and its acrid bust. Kamiya, a former cab driver, is a masterful guide who combines a fluid, encyclopedic knowledge with his own madcap experiences. Cool Gray City of Love is wonderful, and it’s available from SWAN.
