A interesting place is Colma, Ca. It is a two square mile town of 1,600 just south of San Francisco with an underground population of over 1.5 million. In 1900, SF banned any new cemeteries. In 1912, when rebuilding after the quake, they started digging up the graves there and moving them to Colma. Today in SF are only three cemeteries left, the military cemetery at the Presidio, at Mission Delores, and the Columbarium (cremated remains-above ground).
Colma has 18 cemeteries. Some of the famous people buried there are William Randolph Hearst, Wyatt Earp, and Joe DiMaggio. The motto of the town is; "It's Great to be Alive in Colma."
