Throughought Chicago Saturday, demonstrations remained relatively small. Scattered groups of protesters gathered in some neighborhoods, including several hundred who marched to the mayor's house.
Late in the day, another group gathered in the Loop business district and marched down the city's famous Michigan Avenue. Police on horseback and bicycle kept them away from diners at outdoor cafes who ventured downtown despite wide-ranging security precautions. Some vendors reported seeing only a fraction of their normal business.
The largest protests are expected Sunday, when thousands of people are expected to march from a band shell on Lake Michigan to the McCormick Place convention center, where NATO delegates will meet to discuss missile defense, Afghan security and the future of the military alliance.
