Early morning in the half hour before and after sunrise is one of my favorite times for driving along the Ohio River looking for something to see. This morning I saw two boats -- the Paula Ruble and the Wally Roller. First, a few pictures of both boats as seen during that golden hour.
Now here's my question. What was this thing at the head of the Wally Roller's tow? For some reason my autofocus didn't work as I had expected. I can make out the word "Siemens" on this piece of machinery, but that's about it.
Any information would help satisfy my curiosity.
