Via S.S. Trudeau we get a link to the Common Census map, drawn not by political boundaries, but by influence. Influence in this case is measured by respondants to the (brief) survey about what you feel is your community.
This is a very interesting map and illustrates a commonly held perception about Michigan; that of the sphere’s of influence within the state. I wonder if this holds true for the other regions of the country.
Check it out and contribute; it’s only as good as people’s input.
