Chicago is the home of the blues and the truth of jazz, the heart of comedy and the idea of the skyscraper. Here, the age of railroads found its center, and airplanes followed suit. Butcher of hogs and believer in progress, it is one of the world's great cities, and yet the metropolitan luxuries of theater, shopping, and fine dining have barely put a dent in real Midwestern friendliness. It's a city with a swagger, but without the surliness or even the fake smiles found in other cities of its size.
