Sadly, most of these places don't allow cameras for liability reasons, a policy I find ridiculous. I see no harm in publishing my photos now since every car in the pictures is long gone. Even the yard they were photographed in is now defunct. Please forgive the less-than-stellar photo quality produced by a disposable film camera and a 1.3 megapixel cell phone camera. Here are my best California junkyard sightings from the eastern Bay Area (that I managed to photograph).
1951 Chevrolet coupe
1963 Rambler Classic 660
