Chicago, Illinois
Chicago's parade rivals New Yorks, drawing in up to 2 million people. While the green river is always a sight to behold, there are a bunch of great Catholic spots as well. Assumption Catholic Church contains a relic of St. Peregrine for veneration; St. Hyacinth's Basilica has over 100 relics, including one from St. John Paul II; and the National Shrine and Basilica of Our Lady of Sorrows exhibits a full-sized replica of Michelangelo's "Pieta."
