Based in Long Island City, Brooklyn Grange also has a farm in the Brooklyn Navy Yard, which I recently got to visit. It was started in 2010 by a team of urban farmers including Ben Flanner, who had run the Eagle Street Farms in Greenpoint. I visited that farm years ago for a friend's book release party and remember being completely amazed by the feeling that you could stand in the middle of a row of vegetables, on a roof, and look at the New York City skyline. It was surreal.

Now, we’re in a bit of a boom for urban rooftop farming.
