The BosWash megalopolis is the name for a group of metropolitan areas in the northeastern United States, extending from Boston to Washington and linked by economics, transport, and communications. The high-speed Amtrak train, the Acela, runs the length of the BosWash area.
BosWash contains a reported population of 44 million, or 16% of the population of the United States, and four of the world's fifty largest metropolitan areas — Boston, New York, Philadelphia, and Washington.
The geographic trend was first identified in the 1961 book Megalopolis: The Urbanized Northeastern Seaboard of the United States by French geographer Jean Gottman.

I would NEVER live in the Boswash region: the people suck and so does the traffic and weather.
