It does suck. Atlanta has recently designated some parks as "smoke free" zones as well. My favorite example of this is a strip of grass and trees down the middle of a residential street that was labelled a "park" with no smoking signs every hundred feet or so.
I can understand a few of the smoking bans, but the constant push toward banning smoking everywhere is absurd. If I want to enjoy a smoke in my carport I should be able to, I'm on private property after all.
