The New York Times has an amazing interactive fan map that goes further than other college football fan maps have in the past. This one allows you to zoom down to a zip code level to find out precisely who your neighbors are pulling for. Facebook Likes data was used to compile the map.
We have some hesitations about North Carolina, among other things. The Tar Heels didn't list as a single zip code's favorite team in NC, despite having a large Facebook page, with Duke dominating much of the map. We have reached out to the New York Times for comment.
