My son and I went for a late night swim last night. The water was warm and the air as humid as a hot shower. But the noise was deafning. An unknown number of ffrogs or toads and their babies were in full voice chorus and could have been yelling at 70 decibels. We had trouble trying to talk to each other but the moment we got out of the pool they all went dead silent. The transition was instantly abrupt as only the sound of our splish splish foot steps could be heard. When the door closed one probably said 'Everyone back in the pool'.
