Dick's Towboat Gallery has photos of the new Marathon towboat the Kentucky. Whenever it gets up on my section of the Ohio River, I'll try to get some photos, although winter is a hit-and-miss time, considering weather and river conditions.
When Adam saw the photo, he immediately noticed that its ID number started with 121, where the newest boats nowadays start with at least a 122. So he did some checking and found that the ID numbers of the Kentucky and its sister boat the Detroit are sequential. Mystery mostly solved.
