Haunted Los Angeles

Maybe, there aren't as many ghosts in LA as there are in New York or New Orleans, but the modern ghost hunting hobby really started out there.  Mostly it was geeks who worked in the aviation industry that was so stong in SoCal from the 1940s to the mid-1990s.  These guys, and they were almost exclusively guys, had the know how required to invent the first real ghost hunting equipment.
