GO GREEN: Today's the day the Chicago River turns green (watch the dye job near Columbus Drive at 10:45AM), and the downtown St. Patrick's Day Parade marches (step off is at Columbus and Balbo drives at noon). Both are Chicago traditions, and neither is to be missed. Free.
CAN'T STAND THE HEAT: Head to Carnivale today to learn how to make two Latin classics -- ceviche and guacamole. Executive chef Mark Mendez will lead the lesson while students enjoy seasonal mimosas. 12-2PM, $25 per person.
