Fresh evergreens are abound on the buoy deck of the Coast Guard Cutter Mackinaw as the ship serves as the Christmas Ship in Chicago Dec. 7, 2013. More than 1,200 Christmas trees were offloaded today during a two-day re-enactment of a Chicago maritime tradition dating back to the late 1800s and early 1900s.
