Fog bank rolling in

We had another wonderful day and I relaxedly waited till 6 pm to go out for a blip. Took Maggie and we headed for the beach, sun shining brightly in the deep blue sky. Only 4 miles down the road I saw that a big fog bank had developed and was already creeping up the river. I knew that I would not have many photo opportunities on the beach and stopped quickly to document the fog above Florence old town rolling in. We went for our walk on the beach but could barely see further than 10 yards...
