Yeah I know, facebook is the devil. I just thought this was interesting. It shows the rooting interest by county for each region, plus they show the rooting interest by county for three rivalries: Duke-UNC, Michigan-msu, and Kansas-KSU. The Michigan-msu split will probably make you chuckle.

The Michigan / MSU rivalry map is inconclusive because it's only of the U.S. A conclusive map would have to include all the galaxies that are in the MSU recruiting footprint.
That aside, the U.S. map (and the State of Michigan in particular) seems to have a pleasant maize hue, with relatively few patches of green. Unsurprising, but gratifying all the same.
