NEITHER RAIN NOR SLEET nor gloom of night shall stop smokers from getting their fix o' nic, so what do you think is going to stop cigarette smokers on a picture perfect fall day?

The cloud of smoke from Peter Hurd's lungs almost matches the white blossom tree scene on the mural behind him at 13th and Pine.
