Flatbush Avenue is the Broadway of Brooklyn. It slips from one neighborhood to another and another and another, from the Manhattan Bridge until it reaches Marine Parkway near Kings Plaza shopping center. Brooklyn's other main roads, like Ocean Avenue, Linden Boulevard, Empire Boulevard, Utica Avenue, and Eastern Parkway, all have an end at Flatbush Avenue. But Flatbush Avenue is more than a thoroughfare. It's a place where people flock, either by choice, by economics, by culture, or just because.
