Snakes? Even in church.
It's how the Smoky Mountains got their name.
Also, Flatt & Scruggs's band, the "Foggy Mounain Boys".
I kinda remember these things from old tourist brochures and
National Geographic magazines, and suppose I
could google these things, but I don't put a whole lot of time and trouble into these stories.
I'm guessing mountains, trees, a sort of a blue mist or fog; but I don't imagine it's moonshine country--that seems to me it'd be further north and west of where dear sweet old Lu and bewhiskered Bill with the faded overalls live. Also, I
suppose lumbering's a big deal there, as I got bewhiskered Bill working at the sawmill.
As for the wildlife, I know next to nothing; I'd figured maybe it was like Connecticut or Maryland, all paved over and lawned over, so not even a mouse can be found. But then I figured no, it's red territory, so there has to be some real nature down over there.
However, I don't imagine they have cockroaches there, and so left them out of the story.
Dear old sweet Lu's bewhiskered Bill is definitely a different sort of critter from the hippywife primitive Mrs. Alfred Packer's hippyhubby Wild Bill; about as different as day is from night.
