This is the 2nd edition of our popular Boston map, first introduced back in 2010. The 2nd edition covers a much larger area than before, extending from Medford and Malden in the north all the way down to Dedham, Milton, and the Blue Hills Reservation in the south. Watertown marks its western extent, with the airport and harbor forming the eastern boundary of the map. This means that we now include over half a million more people on the map than we had previously! In the center of the map is the entire city of Boston proper, along with Cambridge, Somerville, and other towns across the Charles River.
