The Chicago Air and Water Show is coming up soon. On Saturday & Sunday, August 20th and 21st from 10 a.m. to 3 p.m., at North Ave Beach, residents from all over will leave their Chicago homes to enjoy a great time outdoors watching as the U.S. Air Force Thunderbirds, U.S. Army Parachute Team Golden Knights, and U.S. Navy Parachute Team Leap Frogs perform daring stunts at speeds of 120 mph from 12,500 feet in the air.
