The huge cargo ships that travel the Savannah River impressed me when I first saw them and continue to impress me today. These ships are gigantic. Each of the rectangles on the deck of the ship is a trailer from a semi-truck, giving you some sense of the size of the ship. Seeing them up close and personal gives the best perspective. The second shot of the tug in front of the cargo ship may provide an even better sense of scale. You can see the tug pilot in the cabin.
