In typical fashion for a city filled with bike enthusiasts and brewers, Hopworks Urban Brewery is hosting a free, all-day bike-in Oktoberfest on September 19. The March Fourth Marching band will be playing some sick jams and the Sprockettes, a bike dance troupe, will be there too. I have no idea what a bike dance troupe is, but it sounds both entertaining and dangerous (two things that generally make for a good performance).There will also be a plethora of other bike related activities for the whole family, some more live bands on a "keg-supported stage" and two new organic beers being unveiled. It's a little overwhelming just typing all of that. Bring your bike, grab a beer and try not to crash on your way home.
