Not Indiana but small little town, Mayberry North Carolina. Great place grow up , good haircuts and really friendly gas station attendants.
Talking dog may have went national but not sure.
I'm from small town Mayfield, OH and we had a barber there named Andy, who said his identical twin brother Floyd was a barber in Mayberry, NC. Does that name sound familiar? Have you ever heard of Floyd?

Everyone got a good chuckle the day Andy shaved Wally. A few years later, Andy shaved the Beaver and pretty much most of the town was in an uproar for some reason. It was the mid-1960s after all.
