I'm a smoker and I've seen this coming for the last few years. I try to be a respectful as possible to people who don't and I keep to my little corner of the world and abuse myself. Those people who don't respect designated areas, still won't. Those who always have, will. I actually liked when they reduced the spots in the parks since I ended up smoking a lot less.
I think the really issue is where they put the designated areas outside the parks. Outside MK there's a spot by the bathrooms on the way to the buses. If this will be the official spot now, do you really think people are going to walk from Main St all the way there, then wait in line for security and ticketing? No, those people will sneak it in the park. Rude, uncaring people will always be rude, uncaring people.
