I heard something that I could only compare to a trumpet or some other kind of horn between 9:00 and 9:30 yesterday morning. I'm in the northwest suburbs of Chicago. Came here to see if anyone else heard it but no threads. So I thought maybe someone was just goofing around, getting an early start for the super bowl? Like people who blow off fireworks BEFORE the fourth of July. Did anyone else in my area hear it?
