I'm not understanding how the cities are chosen. For example, Madison, WI (home of a Big 10 university where probably more than a few folks here went to school) is non-existent, but Fitchburg, Middleton, and Sun Prairie, three suburbs of Madison are included. Madison is the second largest city in the state. Just for giggles, I looked up Michigan, and the second largest city (Grand Rapids) is represented even though it's a smaller city than Madison.
That's a somewhat random example from me searching for cities folks here might know, but it's certainly odd.
