Donal G McAllister kicks up some bow action off Bethlehem Steel's Sparrows Point steel mill, once the largest tidewater steel mill in the world... You can see the ore bridge crane in the full view.

Don't worry about seeing this view again; Sparrows Point has been demolished.

I think all McAllister's tugs on the Chesapeake Bay use EMD engines, although a few up north might still have Alco 251s.
