I think even the District of Columbia may be hard pressed to match the summertime din found in Arkansas in the summer. You literally can't hear a conversation if you're outside in a campground around July and August. This is what my kids and I found in mid-Arkansas, around Lake Ouachita and the Hot Springs area. Everything is making a racket.

Here is the Washington Post cicada cam. It's dark right now, but today it was set by a tree and you could see a fence and the tree covered with the things.
