I was amazed when I learned (from the net) that in 1900 San Francisco banned new cemeteries. But they didn't stop there: eviction notices were soon sent out. And from 1902 to 1947, bodies were moved out. Headstones were rounded up and dumped along the shores.

Many of the bodies wound up in Colma ... which now has 17 cemeteries, 73% of the city's land.
