Have you ever been far away from man made noise and light, to hear an almost complete silence?
I was in Yampa, Co. area back up on an old abandoned mining road, fairly high altitude one evening, after Sundown, no moon, no manmade light visible that I could tell, just stars, no wind. All I could hear was ringing in my ears. I was kind of disappointed that my ears could not hear the silence. I did not realize until that moment that there was so much noise and clutter in life, even in the small town I live in. We are exposed to manmade noise and manmade light almost our whole life. You can not hardly escape it.
I still prefer the ringing in my ears, over city noise though.
