From our house it's mostly a distant drone of pharaohs from woods a few hundred yards away, and a few individuals closer here and there. But driving yesterday just a couple miles away the noise was suddenly astonishing at a red light, even with the windows up. I put them down and could not believe the noise. It was cassinis and they were all over a stand of big cherry trees. The hissing buzz-saw sound was unreal. I can't imagine the people that live right near that spot. Then at the next light very little noise.
