Good catch Dave! LOL

... the one behind the Cadillac. I've never owned a Ford but I think I can tell the difference between the grille on a 1953 model and the one on a 1954 model.

Actually VictrolaJazz, we were both a bit off. I called the Ford a "2 door post" as a slang reference vs. "hardtop" the correct connotation, per a 1955 Ford brochure is "Club Sedan". The 4 door was a "Town Sedan". The Victoria was 2 dr hardtop (no B pillar - I owned one once) and the "Crown Victoria" had a chrome strip across the roof that ran down as a B pillar. Anything with the chrome dip on the front door is a Fairlane. Just call me a pendant!

[Ok -- you're an earring! - Dave]

Is a Fairlane Victoria coupe, not a post sedan as one poster noted. The days when there was "a car for every purse and purpose" as stated by Alfred P. Sloan, one time president of GM.

... at Orchard Avenue and Carlos Bee Blvd. (formerly Hillary Street) in Hayward. Thanks to Sagitta and tterrace for their superlative sleuthing.

From the 1958 Hayward phone book, by way of tterrace:

And from the 1961 Hayward Yellow Pages, where the dining options include the Spin A Yarn, Stop 'N Chat, and Snack & Yack:

Clues are few to none. I’d like to know how he/she figured it out.

A nice looking 1949 Cadillac convertible swinging through the intersection in front of a '53 Ford. Looks like a Peugeot behind the Ford, followed by a '56 Chrysler. A VW van and couple of shoebox Fords down the street - one coming, one going. On the far righthand curb a '57 Ford wagon and, closer, a 1959 Ford Ranchero. Over by the drive-in, a '55 Ford two-door post.

Mountains (foothills?), wide straight roads, convertibles, vacation trailer rentals. All that is missing is Broderick Crawford of the California Highway Patrol pulling out of the Burger Joint. The Ford Ranchero being product placement for the rolling shot of him leaving.

At least according to the 1957 Hayward city directory.

The trees have grown since then, especially that redwood a few doors down!

[Excellent sleuthing! You found the city, but we think the address is 24919 Mission Boulevard -- by 1958, there were two Rondale's Burgers in Hayward. - Dave]

There appears to be a Ralph's grocery store down the road from the burger joint, there's a VW microbus approaching (which gives a West Coast vibe for a picture from the early '60s), and the out-of-focus license plates look like they're kind of dark so they could be the old gold-on-black California tags.

[It turns out that this particular Ralph's is an appliance store. - Dave]
