The U.S. Coast Guard Cutter Alder, homeported in Duluth, Minn., sits moored at the Navy Pier, while volunteers stand in line to carry Christmas trees to waiting trucks before being distributed to Chicago-area families, Dec. 3, 2011. The Alder acted as Chicago's "Christmas Ship," transporting more than 750 trees from northern Michigan that will be distributed by different charity groups.
