Quiet has its own sound.
Here I am, far away from highways or other human disturbances and the night is extremely noisy. The last of the Katydids and some other little invertebrate beasts of the night are rattling their exoskeletons to the base line of the nights music. Not much happening in the midrange but the tweeters are working up a frenzy on the edge of my high pitch hearing range.
Soon the cold will come and change the song of the night. I think I'll try to get in one more swim in the hot part of the day before that happens.
