68krrrr,
That's a cool photo of what looks to be Van Nuys Blvd. I have seen it before, on the internet with a bunch of other "Cruising Van Nuys in the 1960s and '70s" photos.
The tip off for me that it's Van Nuys is the triple-head style of streetlights. As far as I know, Van Nuys and Hollywood Blvds were the only two streets in SoCal (in that era) with triple-head lights. Probably installed as a supposed way to combat cruising. (I can attest to how well that did not work.)
My buddies and I regularly cruised Van Nuys in the mid-late 1970s, but I can't remember when we were lucky enough to have two shapely blondes like those girls stop to admire our muscle cars. Hmmm...maybe I needed a '67 Mustang GT.
