The wind moves Chicago. All of it. Trees tilt softly then with vigor. Some bicyclists ride defiantly against the wind, while others pedal delicately - but they all stop periodically to rebalance. People check that their beanies have not been blown away. Even the buildings sway gently.
And the leaves dance. Giant swirls of red and yellow rising, racing, falling, exploding. I walked through a park in Chicago on a windy Autumn day and felt as if the leaves were performing just for me.
