The throngs of voters who declared they couldn't go into establishments which allowed smoking are still not going in. And neither are the smokers. I heard from a bar owner friend that at least two Rapid City bars will be closing soon, with multiple employees left without jobs.
I've been to Deadwood twice since the ban and it is nothing short of catastrophic. If you're among the 63 percent who voted to ban smoking in bars and casinos, I recommend you get your wallets out and go patronize those businesses or prepare for a state income tax to make up for the gaming and bed and booze tax revenue lost.
Prepare also for significant changes in this legislation in the future.
