The Adler Planetarium is also set among the museum campus and is worth a visit for space lovers. Art, history, and science buffs will love a day trip to the museum campus, though you could spend days exploring all of the Art Institute of Chicago alone-you may not make it to the Museum of Science and Industry or the Field Museum. Lovers of high-end shopping can visit the Magnificent Mile and browse high-fashion favorites. The Second City has world-class offerings for everyone. The CTA’s Orange Line “L” train can speed you directly into the heart of the city-or you can work your way to wherever you’d like to go across Chi-Town. When visitors deplane at Chicago Midway International Airport, the movement begins immediately, whether the conveyance into big-city adventure is a rental car, a called car, or the city’s sprawling public transit system. Standing in the Loop-what Chicagoans call their downtown-you certainly do get the feeling that you’re at the center of something thriving with nonstop motion. Since its settlement, Chicago (Midway) has been a major transportation hub.
