It's the Cicadas!


Don't panic if you start hearing a strange high pitched whine. 

Your system is not suffering a catastrophic failure. It's just those bugs screaming for sex.

Experienced them twice in Iowa (moved West when I was 22).

Shiny, loud, somewhat creepy and painful when one flies into the side of your head.

Boy howdy have they been coming up out of the ground! Some are maybe an inch and a half long and the others are about two inches long and it’s getting noisier and  noisier around here!

I've been screaming for sex for years now, but my wife always says it's the cicadas.

I moved from the North Shore 20 years ago and haven’t been to Ravinia since.  I now live in the Oak Park area and we go to Grant Park in the summer for live music.  You get the city noise-nothing like ambulance siren to disturb a solo flute passage-but I remember this Ravinia cicadas as being deafening, particularly in late August.
