Fog is a collection of water droplets or ice crystals.........................

............suspended in the air at or near the Earth's surface.  Yes, this morning might have been the foggiest morning I have ever experienced.  Visibility at one time could not have been more than 5 feet.  I know since I had to drive in it.  No, not just to get my shots.  I was working.  Yeah, that's it.  I was working. Anyway, even though my eyes saw heavy fog everywhere, I still have a hard time capturing it.  Tonight's shot doesn't do justice to the amount of fog out there, but it was a pretty scene anyway.
