Foggy river

It's been pretty foggy around here the past few nights. It's been clear during daylight except on the river. The fog hangs over the river only and stops at the water's edge. It's been that way for three days at least.

On Friday I saw the R. Clayton McWhorter entering the Robert C. Byrd locks in such a fog. I had only a phone camera with me, so the pictures weren't so good. But yesterday Adam and I saw the Bill Carneal in the same spot. This sequence of photos taken just a few minutes apart shows how the fog came and went.
