What you need to do, if this is such a burning issue with you (and believe me, I understand why it is-I'm pissed off about it, and don't live there) is to somehow get your message across to those who would be inclined to go to those casinos, via flyers, newspaper ads in the classified section, getting on local talk radio, whatever. You'll probably just be pissing into the wind, though, because, as you say, smokers everywhre are becoming desperate to go out somewhere and relax among other smokers. And the Indians of course know that.
I did consider writing letters to the editor or something... because not everyone is aware that the tribes were actively funding this... Whether I actually will do it, I don't know...
What's the point, you know? I feel for my local pub I used to go to, because their sales will hurt, their jobs and tips will suffer. Those working the casino bars are just out tryin' to earn a check too. They weren't involved in the Tribal PAC... And people go to the casinos for a lot more than just to find a place to smoke. It's just depressing. I want to go out to my local pub a few times before this gets enacted, so I can smoke and tip them well... they'll need it.
