Massachusetts Bay Transportation Authority (MBTA)Boston has an extensive public transportation system which makes it easy to get almost anywhere in the city or suburbs. The MBTA just redid their site with Google maps, so you can see where all the subway and bus lines are relative to streets in Boston. They even added a trip planner feature, so you can enter your start and end locations and be given several public transportation routes.
