Very cool, David!
I was just at a bbq that lasted from 3pm until after midnight. I heard a lot of similar sounds there as well, very cool!
It's a beautiful sound, isn't it Chuck? I don't think the recording did it justice. Those sounds were all around me - even from up above. It's very pretty. I'm glad you experienced those sounds. New Jersey is not all THAT far from Indiana (it's far but not very VERY far) so you all probably have similar insects and animals that we have here.
