ACBL's Tom Behringer has a tow of 12 loads heading southbound on the UMR. Assist tug Mrs. P's deckhand has climbed on the head of the tow and is securing face lines. Often, the assist tug will simply push the starboard head of the tow into the lock; in this case, they're tying on because they will lock through with the first cut of barges. After the lock is emptied, Mrs. P. will pull the first six barges through. This saves a little time versus relying on river flow through the lock to flush the barges out.
