I awoke to another very foggy morning and so set off to see what was happening in a swampy area not far from my home.  The fog was so thick the camera was
having a difficult time locking focus. When there is a heavy fog like this sound goes dead. This morning the only sounds heard were from a fish or two breaking
the surface and a few waterfowl looking for their next meal.  It was very different from what you normally hear on a clear day.
