MM's tale about his family is quite plausible. Family fall-out shelters were a thing, briefly, ca. 1960, +/- a few years. I remember seeing signs in town directing people to the town's public fall-out shelter. Being close to 3 large AFBs, they probably would have been meaningless.
MM is of an age where he could have watched Rocky and Bullwinkle when their cartoons were first released.
I'm a bit less aged, so my family watched The Flintstones on Friday nights. IIRC there was a naming contest for when Fred captured Dino and took him home to be a pet.
