Tens of thousands of wreaths made in Maine have been laid at graves at Arlington National Cemetery. Trucks carrying about 120,000 balsam wreaths began rolling Dec. 8 toward the Washington-area cemetery. They arrived Saturday.

The nonprofit Wreaths Across America, based in Columbia falls, Maine, expects to ship as many as 500,000 wreaths to adorn veterans' graves across the country and overseas this holiday season. Sens. Susan Collins and Angus King of Maine say the Senate has passed a resolution designating Saturday as "Wreaths Across America Day."

The wreath-laying tradition began in 1992, when the owner of Worcester Wreath Co. ended up with extra wreaths and shipped them to Arlington. - AP
