Smokers isolation

I was driving down the beautiful winding tree lined street today on the way to see the construction progress on my company's new building (this is starting out like an Ed post!). I glanced to my right to see a single lonely smoker the requisite distance from her non-smoking building puffing away. It is a very comfortable 55 degrees today so weather in this instance wasn't an issue. That said, in Iowa City where smoking is very restricted, it isn't uncommon to see smokers bundled up, braving the elements of cold February days so they can smoke. It seems that smoking is all at once the most social of habits, along with its close brethren of vices drinking. But seeing the lady this morning made me think that at times, in particular in a community with severe restrictions on smokers, smoking is a very isolating habit.
