In Az they have these little creatures that chirp when the heat is unbearable and the rain is near. I went for a walk today and they were out big time they drowned out the T. The CICADA were out in numbers. About 20 minutes later they all stopped on the same instant, I heard them. Then the T came back. They actually muted the T. I dont think you could listen to their sound for very long. The CICADA are coming! Cchhiirrpp...chirp!
