Coming past monsanto in Springfield on the mass pike late late at night will get you a sweet smell like plasic and apples. I'm sure it's very healthy.
My late brother-in-law worked at that very plant.He told stories that were,shall we say,quite interesting.
And speaking of smells...we used to vacation in Bradenton,FL near a huge Tropicana plant.If you were lucky while driving down SR 64 near the plant,you'd get a rather pleasant aroma of citrus.
It sure beats driving through Newark.
