A new type of boundary

Check out the survey at CommonCensus, which is being used to create a map that breaks down the United States into spheres of influence, centered around major cities instead of traditional state boundaries. Boston's area is pretty huge, encompassing almost all of New England (except for that Yankee territory down in southern Connecticut), but not nearly the size of the western regions, like the one surrounding Denver. The map did sort of remind me of this one that floated around the internerd after the last election. I got the CommonCensus link courtesy of Bostonist.
