May 21, 2012 – Although clashes with police were ahead of them, the mood was lighter on Sunday afternoon as thousands of protestors left Grant Park in the Loop to begin their march south on Michigan Avenue. Their destination was McCormick Place, where NATO delegates are meeting. Monday is the last day of the summit.
