A towering oak tree draped with Spanish moss offers little relief from the Florida sun as Andrew Lumish scrubs grime from the headstone of a World War I veteran.
"It's pretty messy, pretty dirty," he says. "We're pulling out dirt and biological material that's been here since 1921. So, a lot of elbow grease here."
Lumish, who has so far cleaned about 600 veterans' headstones, says he restores them out of respect for those who died and to learn about how they lived.
