Mad City or Madtown might appear to be just plays on its name, but it also says something about its quirkiness. This is a town, after all, that has a National Mustard Museum and named the plastic pink flamingo as its city bird. The latter happened after the University of Wisconsin’s quad was plastered with a thousand plastic pink lawn flamingos overnight in 1979. That flamingo-bombing became an annual tradition and the city’s official bird.
