"Chicago is the third most populous city in the United States. With over 2.7 million residents, it is the most populous city in the state of Illinois and the Midwest. The Chicago metropolitan area, often referred to as Chicagoland, has nearly 10 million people and is the third-largest in the U.S."
Also, Chicago is my favorite city to explore and photograph. Everytime I go there I found myself surrounded by nice and creative people.
