Oh geez those will be coming out soon here in Indiana. At first they're kind of nice, a sound of summer. After awhile though, they're just annoying. I remember my family coming down from northern MI once, and we were sitting out back. My cousin was like "what the hell is that sound?!?!" I always figured they were everywhere.
We have the green ones here with the 2- and 3-year cycles that appear in smaller numbers every year. They can make disturbing squeaks when disturbed, making you think you've started a slow-flying and poorly-maneuvering hummingbird.
