Petty Officer 2nd Class Dennis Ebanks, a member of the buoy deck team aboard the Coast Guard Cutter Mackinaw, a 240-foot icebreaker homeported in Cheboygan, Mich., hammers the head block into into a buoy after the team brought the buoy onto the cutter as part of Operation Fall Retrieve in Lake Michigan, Dec. 5, 2013. The Mackinaw is continuing normal operations as part of Operation Fall Retrieve while serving as the Christmas Ship, delivering more than 1,200 Christmas trees to Chicago from northern Michigan, as the route coincides with the cutters annual seasonal buoy run in Lake Michigan.
