Is it fog or is it smoke?

 I woke up this morning and looked out the window.  I felt like I lived in Snellville, Georgia again  or was visiting San Bruno, California.  Outside I saw this moisture hanging in the air.The fires in our area had been extinguished with yesterday's rain, so I think is is fog. Perhaps it has a little smoke in it too. Anyway, I took 2 photos to remember this day. Now I'm off on my morning walk.
