From the NYT--
"Green grass, blue sky, white headstones — and the Patriot Guard, in line, in leather, holding up their flags. A color guard. A salute from Marine Corps rifles. Taps.
"Who are you masked men?" asked an old-timer in the red garrison cap of the Marine Corps League.
"Patriot Guard Riders," Mr. Deale explained.
"Well, it's impressive," the old-timer said. "Very impressive."
Then the dead man's mother walked the line of riders and, with her son's flag tucked beneath her arm, shook each and every hand."
