As an avid non-smoker I think this new "law" is ridiculous. It's OUTSIDE for crying out loud. Giant exspanses of open air.
I can see banning smoking with-in 25ft of an entrance/doorway (because it is annoying walking past some tool smoking a cig with one foot in a door and the other right outside of it), but this just seems ridiculous.
Either make it illegal (which is really dumb), or quit screwing with the people that smoke. Sooner or later the people that agree with these silly little bans are going to find their guilty pleasure (fast food, chocolate, wine, donuts, etc) under fire, and their tune will change quickly.
