Discovery of Millennium Park has started in all earnest. I need to get to what all makes Millennium Park function and so far it is just one sentence, it makes people happy. Yes, that is what Millennium Park does every time you visit it. Fool around, play around, admire art, admire science, live art and live science, attend a jazz show, do whatever but be happy. That is what is the promise of Millennium Park and that is what is to be discovered.
