Colma, California, is a city with a bit of a macabre history. It was explicitly founded in 1924 as a necropolis - a city of the dead. Graves outnumber living people by as much as 1000 to 1 - and growing!
In 1900, nearby San Francisco passed a city ordinance forbidding the laying of any further cemeteries within the city limits. California being a pretty populated state, that left the question of just what to do with the dead - and so Colma because the great graveyard of San Francisco.
It's a peaceful, if somber, place to live. Just miles and miles of gravestones, crypts, plots, memorial parks, and florists, with about 330 households composed of the living, including those raising families. But the town of Colma hasn't let its largest industry dampen its spirits; in 2007 they put together an independent film called Colma: the Musical which was a smash hit on the indie film circuit.
