I've lived in Baytown & it's full of chemical plants. One can drive only a mile & get 10 different chemical smells. Sometimes they are bad enough to burn your eyes. If anyone thinks that banning smokers will improve the air quality at all, they are either just plain stupid or extremely biased.
Sounds like the town "I" live in! We have a starch factory and it stinks to high heaven in the summer. But the state has forced a smoking ban on restaurants and bars. LOL
