One evening, while in the Tidewater area, we took a dinner cruise on the “Spirit of Norfolk”. The boat departs from Waterside in Norfolk and cruises down the Elizabeth River to the point where it opens out into the Chesapeake Bay. As we cruised down the river, we passed various shipyards and the U.S. Navy’s Norfolk Naval Base. Although the “fleet” wasn’t in port, there were a considerable number of ships in for maintenance or stand-down periods between at-sea operations. With the evening light, the ships appeared to be in various “Shades of Gray”.
