Editor's note: Any city that has not one, but two professional baseball teams is a mega-city, a star to steer by. (Only Chicago and NYC truly fit that definition, because L.A.’s second team plays in Anaheim, sorry L.A.). Aside from being a sports deity, Chicago is overflowing with great museums, restaurants, parks, and cool things like the most complete T-rex skeleton ever discovered. Enjoy our Chicago wallpapers!
