Coming up is the one about Aunt Bea learning to drive. I have always felt that there was a stand-in each time "she" was behind the wheel. And they used someone else who had the same build as her, could even be a man, and they also used the hat as a common focal point so the viewers were duly tricked into believing it was always Francis Bavier. Anyone agree or disagree?
P.S.---Back in the '60s it was not common for women to drive cars. Anyhow, where would Bea go, why would she need a car? And and and it makes it even more odd that she took flying lessons at a later time. Were they running out of plot ideas? Did the series last too long? Is it true Barney was the lifeblood of Mayberry?
