I love it when you suburanites, Rep The Chi. Then I ask "Ohh what neighborhood are you in?" and get .....Schaumburg as an answer.
I think globally its easy to lump them in. not everyone in the world (English speaking) knows where Arlington Heights is, but they do know chicago. when I went to school in Iowa no one new what the **** or where Lake Zuric was, but if you said chicago they new, and then at NIU if you said chicago they wanted to know what 4 corners.
