Things to Do in Chicagoland takes center stage this week with a packed June 8–14 calendar that stretches from Wrigley Field and Millennium Park to Bridgeview, Humboldt Park and Lockport. Headliners include Mumford & Sons, the Summer Smash festival, the Wells Street Art Festival, the Grant Park Music Festival, Puerto Rican Festival and Old Canal Days. Whether you want live music, neighborhood art, free cultural events or suburban family fun, this is one of the strongest Chicago-area event lineups of the summer.
