CHICAGO (AP) — A deluge of 90,000 rubber ducks poured out of a truck on the Columbus Drive bridge and plunged into the Chicago River on Thursday, and then raced at a leisurely pace in the annual Chicago Ducky Derby. The annual event, a fundraiser for Special Olympics Illinois, draws thousands of participants. Becky Cavanagh, the Ducky Derby ambassador and a 13-year Special Olympics athlete, held up the winning duck to the cheers of crowds packed on both sides of the river. Cavanagh said her favorite part about the Special Olympics was “making new friends.” Special Olympics Illinois organizes competitions across the state for people with disabilities and special needs.
