I've only ever spent time there in the summers, but I have plenty of family throughout western Montana from Missoula to Eureka.
It's been some time since I've been up, but I've been wanting to get back up there for the last two years now.
Long vacation. Cigars. Whiskey. Family. Fishing.
Not sure if the nazi regime laws in our "free" state would allow such a thing... but it would be worth a try.
I'm planning on contacting the City Hall this week to find out more information on this, but as bars and restaurants can still allow outdoor smoking, I don't see why this should be a problem. The only concern I can see is the fact that it would be a rooftop and a smoking lounge would naturally require a bar, which would mean there would possibly have to be an alcohol consumption limit for the sake of safety. Also, I worry about the long-term success due to a limited season in which to operate.
Another idea I had is the idea of a private smoker's club. It seems the one here in Billings recently closed down. Since a private club is not considered a public establishment, it bypasses the ban laws...however would require substantial membership fees to operate.
Okay, so it turns out I was wrong about the private club idea. After talking to one the owner of Tobacco Row, where I occasionally buy a stick or two, it turns out the bans also include private institutions, which would explain the shutdown of Myo (I'm still somewhat new to the state, so it's taking some time learn the nuances). But from what I've been able to find, a rooftop lounge shouldn't be a problem as long as it's an open-air venue. The only issue I can see from that point is handicap accessibility, seeing as how building a lift is extremely expensive.
