There's a strong Irish influence in Chicago, so it's no surprise that the city is the place to be on St. Patrick's Day. One of the most famous traditions in the country takes place at 9 a.m. when the Chicago River is dyed green. It's free to watch the process and the color only holds for about five hours, so don't miss it. In addition to having one of the largest St. Patrick's Day parades in the U.S., there are also several free community parades around the city celebrating their Irish heritage.
