Between 1849 and 1851, peak years of the Gold Rush, San Francisco was almost entirely destroyed by fire seven times. And there was something about these fires, at least the majority of them, that seemed somehow not accidental. Some were suspicious because they seemed to start at odd times, or when someone's temper was flaring, or they seemed to break out when, what locals reported as "odd people" were hanging around.
Seven's a lot of fires, and we'll talk about some additional smaller blazes, tooSee omnystudio.com/listener for privacy information.
