Millennium Park

Chicago has some fantastic parks but my favorite by far is Millennium Park. I'm fairly certain this park is so popular thanks to its most famous of sculptures - the Cloud Gate. Of course no one calls it the Cloud Gate - instead it's called the Bean, thanks to its kidney bean appearance. And while the shape is quite lovely, it's the mirrored steel that makes it so awesome.

Fun Fact: Seventy-five percent of Illinois' population lives within commuting distance to Chicago
