This is a nifty experiment being conducted by The Commoncensus Map Project. You answer a few short questions and a map is created that shows the influence of an urban area...which city does one have the most affinity to. They are also doing it with sporting teams. No word yet on NCAA football (supposed to be displayed today)...looking forward to how big of a footprint Penn State has.
One oddity to me in the map is right smack in the middle. People from Sioux Falls are culturally attracted to Omaha. Those in central South Dakota are attracted to Sioux Falls. I guess, for those in Pierre, they would go to Sioux Falls for a good time...and those in in Sioux Falls would go to Omaha. Maybe the map will shift once more people participate.
