There’s a wonderful term for the dirt trails that people leave behind in parks: desire lines.
Cities also have desire lines, marked by economic development and evolving patterns of travel. In New York, Manhattan was once the destination for nearly all such paths, expressed by subway tracks that linked Midtown with what Manhattanites liked to call the outer boroughs.
But there is a new desire line, which avoids Manhattan altogether.
It hugs the waterfronts of Brooklyn and Queens, stretching from Sunset Park past the piers of Red Hook, to the Brooklyn Navy Yard, through Greenpoint and across Newtown Creek, which separates the two boroughs, running all the way up to the Triborough Bridge in Astoria.
