Once he's finished stationing his flags, Tony Boyer looks out over the hurly-burly, his hands pushed down in the pockets of his plaid wool jacket. A retired electrical lineman from Keezletown, Va., Boyer cuts an unassuming figure in a camouflage cap, dark slacks and black orthopedic shoes. His weather-lined face looks older than its 65 years. "It's not the age, it's the miles," he says, unsmiling, in a twang that stretches out all the long vowels. "They'll tell you, 'Work outside, you'll live longer.' Don't believe that."
