Oktoberfest refers both to the eponymous, six million person, two-week beer festival held each year in München (Munich), Germany (which actually starts in late September, for trivia fans), as well as the worldwide movement of similar festivals that it has inspired. The largest U.S. Oktoberfest is generally considered to be Oktoberfest Zinzinatti in Cincinnatti, Ohio, with more than half a million beer drinkers. It's likely that no matter where you live in the world, you are a car ride away from an Oktoberfest, so find a designated driver, and hit the road!
