Dumbo stands for Down Under the Manhattan Bridge Overpass and is bound by Brooklyn Bridge Park, the Brooklyn Bridge, Brooklyn Heights, and Vinegar Hill. It was previously a manufacturing district full of large buildings and machinery. Now it is home to artists, technology companies, and residential housing. Dumbo is fairly relaxed with good shopping and dining. Transportation in and out of Dumbo includes trains, buses, and the East River Ferry, which sails from Dumbo to downtown Manhattan in five minutes.
