A crew member from the Coast Guard Cutter Mackinaw helps prepare the ship for tomorrow's festivities after the Mackinaw, serving again as this year's Christmas Ship, arrived at Chicago's Navy Pier with more than 1,200 trees Dec. 6, 2013. Following a public ceremony tomorrow, the trees, which were purchased by the Christmas Ship Committee, will be offloaded and distributed to deserving families identified by the committee.
