Wave

 It's always nice to get a wave from the pilot. 

In this case, it was from the motor vessel Tri State, a smaller boat that works the harbor at Catlettsburg KY. For the most part, it moves around barges for the bigger boats. The bigger boats deliver the barges to terminals on the Ohio River and its tributaries.

Not only did the pilot give me a wave with his hand, but I had to step back a bit while shooting this boat, as the waves from its movement were getting pretty close to where I was standing near the water's edge.

That's one nice thing about the Ohio River. The water comes all the way up to the shore.
