I'd have sunk in the car if Marcus Jetty hadn't been doing a little late-season beachcombing. Marcus runs Greenstone Salvage and Tinker, a famous local eyesore of bike frames, tube amps, hula poppers, oil drums, and knobs of driftwood. He was picking along the jagged strand in his raincoat, eye on a fat cork from somebody's herring net, when a car approached on the highway above. He later described the sounds of a whining V6 and thumping bass line before the barrier burst to shrapnel and the world for a moment muffled itself.
