Here's the mv. Leonard L. Whittington about to go under the Robert C. Byrd Bridge, a.k.a. the 6th Street bridge, over the Ohio River at Huntington, W.Va., this week.
I particularly like how the water changes color as the barges pass through. It's mostly brown because of the heavy rains we've had this past week. Somewhere a professor has a chart of the depth of the photosynthesis zone as it varies with increasing turbidity. But I'm not looking for it right now.
