Dumbo, which stands for 'Down Under the Manhattan Bridge Overpass,' is a neat neighborhood in Brooklyn that is at an awesome vantage point of Manhattan. There are cool rocks on the shore of Brooklyn Bridge Park that are fun to relax on and sneak alcoholic beverages.
NYC's skyline has been drastically changing, and Frank Gehry has added a real masterpiece with 'New York by Gehry at 8 Spruce Street'.
