Twenty-four thousand holiday wreaths are being laid to honor veterans buried in Arlington national cemetery.
It's the 19th year of the Arlington wreath project, which gave birth to the wider wreaths Across America Program.
In addition to Arlington, wreaths are being placed at 550 other cemeteries across the US and the world.
Thousands of volunteers are taking part in the Arlington event.
One of them, a Virginia resident, described what he does as he lays each wreath.
“I read whose name was there, and their dates and said a thank you, these are men and women who have given the ultimate; all gave some, some gave all,” said John Royster.
Wreaths Across America is a non-profit organization that began in 1992 when a Maine couple who runs a wreath company donated a surplus of 5,000 wreaths to Arlington cemetery.
