When I was growing up in Clifton, NJ, humid days were an occasion to smell one or both of our town's whiffy manufacturing concerns: Hoffman-LaRoche, with their funky B-vitamin scent, or the overpowering Wind Song odor of the Givaudan-Roure site. Recent air-pollution legislation has forced these companies to be a lot more stringent about how they perfume the New Jersey skies, but opening a bottle of multivitamins will forever spark childhood memories for me.
