The exteriors were filmed on the Warner Ranch. Many familar sitcom homes are in the driving shots. John Dayton who plays the teen boy who catches the Andersons kissing went on to be a very important member of the production crew of the Waltons
The Anderson family vehicle is a brown station wagon with blue California license plates, numbered 042-BAK. These license plates obviously predate California's issuance of seven-digit license plates.
Interesting to note that by the time of the "Father Knows Best: Home for Christmas", 7 months later, the brown station wagon now had a license plate number of "781-AMC".
