Rows of headstones at Arlington National Cemetery.
More than 400 people from 30 states are expected to roll up their sleeves and get to work for the 16th annual Renewal & Remembrance Day at Arlington National Cemetery Monday.
They'll be tackling several projects, including an upgrade to the cemetery's irrigation system. Event chairman Walter Wray, a landscape contractor from Bethesda, says the upgrades reflect a change in philosophy about irrigation.
It's a move away from sprinklers broadcasting water over wide swaths of land toward a more targeted approach.
"We're adding a lot of different heads and emitters in places where they used to count on one large rotor to cover a large area," he says.
All of the materials and labor will be donated. Wray says it's a way for landscapers to recognize those who have made the ultimate sacrifice.
"It's just a great way to give back to our country, and to improve the landscape of some of our most cherished and hallowed grounds here."
The event begins at 7:30 am.
