yup, this is la
I lived here for seven years before I ever discovered this part of LA. This is the Point Vicente Lighthouse at the tip of Palos Verdes. It was built in 1926 and is a good spot for whale watching (we didn't see any). For those of you that don't live in LA (and I know through sitemeter that most of my visitors are from outside here), one of the cool things about living here is there are so many places in LA that you can find yourself feeling like you're not in the middle of LA, but you are. This is one of them.
Here are a couple sites for more info - the first one is pretty interesting and detailed about this and other lighthouses in CA and other parts of the country...
