In a city with its share of things that smell bad -- the Purina facility, the stock show grounds and the police department, to name a few -- it's a welcome relief every so often to sniff something sweet. To that end, when the wind is just right, the Jolly Rancher plant gives off the tantalizing scents of grape, apple, watermelon and other fruity fragrances that fold down out of Wheat Ridge and settle in northwest Denver. The company, which was founded in Colorado in 1942 by Bill and Dorothy Harmsen, is now owned by Hershey. It produces fifteen million pieces of candy a day. Just call it aromatherapy that doesn't suck!
