In this Dec. 18, 2012 photograph, the sun sets on the river vessel influenced Lower Mississippi River Museum in Vicksburg, Miss. The museum provides visitors with a extensive look at life surrounding the Mississippi River through several centuries by way of its interactive and static displays. Visitors also have the opportunity to tour the Motor Vessel Mississippi IV exhibit and see how crews worked and lived on the towboats used by the U.S. Army Corps of Engineers. (AP Photo/Rogelio V.
