I lived in Balboa, CA during WWII and remember that the streetlights were all blacked out on the ocean side. My mother also made blackout curtains for the house and I remember riding with my aunt at night using only the running/parking lights on her car. The Japanese did indeed have submarines that made it to the west coast. They were able to lob a couple of shells at the Elwood Oil Field just north of Goleta. They did little real damage but it was a psychological scare. Some of the wood from the old Elwood Pier that has shell damage is in The Timbers Restaurant building at Winchester Canyon Road just off of 101.
The SP (Now UP) line runs very close to this spot.
There is, by the way, still an SP sign on the overcross at Hollister Avenue in Santa Barbara. it's pretty weathered and has had some graffitti damage but it survives!
On another note, I drove through Gaviota yesterday and saw firsthand the devastation that the fire caused. You'll remember that this closed down both north and south bound Amtrak and UP traffic for several days.
