If you hear thunder but the sky is blue, Aug. 16, it is likely the U.S. Navy Blue Angels are flying overhead on their way to practice above North Avenue Beach.
The Chicago Air and Water Show, now in its 61st year, will be above and on the popular beach from 10 a.m. to 3 p.m. Aug. 17-18. By the way, the U. S. Air Force Thunderbirds headlined last year.
The event is free but given that it attracts about two million people those two days, it makes sense to go the day before when the headliners and acrobatic flights are practicing.
Tip: All the fly-bys are great but the top draw this year, the Blue Angels, come at the end of the show.
But an alternate to going the day before or milling with the crowds during the show is to watch from somewhere between Ohio Street and Fullerton Avenue such as the places listed below where you can eat lunch or brunch during the show.
