Yesterday we got a rare opportunity to take a look inside the Brooklyn Navy Yard, during the annual Brooklyn Navy Yard Arts Open Studios day. Dozens of artists opened their workspaces to the public, and in between visits, we got to snap some pictures of the southern three-quarters of the yard. With over 300 acres, many streets, and a huge number of buildings of all shapes and sizes, it's hard to get a handle on the vast size of the place-- but these pictures should start to give you an idea. If you want to check the Yard out for yourself, the Brooklyn Historic Society is set to begin their tour program in November.
