Tank Farm Terrorism. Jack takes 3 kills. Derek gets disgusted. Chloe is relieved. In the real San Fernando Valley of L.A., there is no tank farm at this intersection. Trust me, I used to work a few blocks north. Also, Jack said Variel, but that street does not cross Topanga, so we picked a close fit. But there are plenty of these tank farms in the South Bay of Los Angeles, which is probably the filming location. More arcane trivia on 24, Los Angeles, and each photo posted on Flickr. Just click on the picture and off you go.
