My best guess is a total makeover for the polite smoker who only rarely smokes in public.
amazing thing is more of these type bans are being defeated than enacted - they just don't get the same media hype.
While entire states go for a ban a few towns that were over zealous exceeded the authority they had or they didn'tike the folks smoking in the streets. These towns didn't change becuase the voters wanted smoking in restuarants or because they were honoring private property rights. Its just a matter of time that either the controlling state law will change to allow other towns to extend a ban and the towns that didin't want street smoking figure out a plan B. Either eay these wins are more strategic retreats.
