Universal backlot
I think the street used for filming is called "Colonial Street" where "Desparate Houswives" (Wisteria Lane) is filmed. I can see "The Munster's" house in the background. A couple of years later, "Leave It To Beaver" came on the scene. Is Cary's house the Cleaver house? Cary has a front porch and balconey on her house, but I think it's the same facade, isn't it?
