Milwaukee needs to listen to the people on this one. Have you seen their current flag? Plus, this current one is so good. People have even printed it off and begun hanging it out about town.
Similarly, Sioux Falls has no flag, but there is a popular movement to adopt one. I have gone to church right next to a flag factory, and they have the proposed flag flying outside on their parking lot. Go look it up. I might discuss that one tomorrow. I am also strongly considering buying my friend one of those flags for his birthday (he lives in Sioux Falls).
