I live here and I won't be spending MY money anymore in a restaurant/bar/tavern that cannot accomodate all the peoples. And that includes smokers. I can stay home and order in and have a party where everyone are equal. Be they smoke or not!

And they did in Delawre which has a much more outdoor friendly environment than Maine. (unless you are a skier or a bear)
