Why is one of San Francisco's fire hydrants painted gold? What are two Dutch windmills doing on the edge of Golden Gate Park? And what does one apartment on Telegraph Hill have to do with the CIA, mind control, and the "Summer of Love"? Join us on a one-of-a-kind tour of the City by the Bay as we seek out the city's most remarkable and surprising secrets, many of which are hiding in plain sight. Our journey includes a bakery made famous by the Gold Rush, landmarks of the 1906 earthquake, and the evolution of the rainbow flag.
