Throw in some tree frogs...and you got a concert.
I usually camp in my RV. Our family decided they wanted to experience sleeping in some tents in a national forest. It wasn't too hot so I was game. Round about 2 in the morning all the bugs and the frogs and the chirping and the buzzing and every other sound -- drove me nuts. I got no sleep that night.
Hawaii. Tree frogs. They are so loud.
