There are very few consumer goods that sell themselves these days. Cigarettes (gross), hookers (grosser) and beer (deliciousest) are the first three that come to mind, and only one of those deserves any sort of commemoration. That's exactly why there's the Cincinnati Beer Festival this weekend at Fountain Square. The beerstravaganza kicks off Friday with more than 200 different flavors of beer provided by big beer names like Guinness, Mt. Carmel, Christian Moerlein, Leinenkugel, Left Hand and Thirsty Dog.
