There’s no greater equalizer among the world’s billions of city-dwellersthan the eternal struggle to navigate the particular structural challenges of your given metropolis. New Yorkers are intimately aware of this, from the rapidly deteriorating subway system and multiplying bike lanes, to the resurgent fleet of ferries churning along the city’s waterways. These unique (and not-so-unique) issues are the focus of the Van Alen Institute’s upcoming festival, FLOW! Getting Around the Changing City, which will combine conventional discussions with urban journeys; like exploring Brooklyn by way of its bike lanes, or pondering the extremes of affluence and poverty along the route of the M101 bus line.
