That subtle drop in the mercury and the sudden reapparance of your favorite cardigan can mean only one thing: it's time for Oktoberfest.  Or should I say Oktoberfests

I should, because this year, there are more O'fests (and Harvest fests, Pumpkin parties, etc) than you can shake a stein at.  Check out our handy synopsis for all things autumnal.  And feel free to add anything we missed in the comments.
