>No, many bars still allow smoking.

Where, exactly, is that the case?

I've traveled all over the US and haven't been in a bar that allowed smoking indoors in at least 15 years. And as a smoker, I would definitely notice.

Edit: As kube-system pointed out[0], there are a bunch of places that don't have indoor smoking bans. Although the Wikipedia[1] link they provided does say that ~80% of American live in a place with some restriction on smoking indoors. I stand corrected. Thanks kube-system!

All of the south except for NC has no state bans on smoking in bars, although many major municipalities ban it.

Specifically I've been to bars in Tennessee and Florida in the last 8 years that allow smoking inside, as well as a diner in Kentucky that still had a smoking section until a few years ago.

Mostly pool hall sort of places I'd imagine.

Really? I did not know anywhere allowed indoor smoking. There are even states that have banned smoking in hotel rooms.
