Book excerpt: Venture off the beaten path down forgotten roads and discover where a hidden South Carolina exists. Time-travel and dead-end at a ferry that leads to wild islands. Cross a rusting steel truss bridge into a scene from the 1930s. Behold an old gristmill and imagine its creaking, clashing gears grinding corn. See an old gas pump wreathed in honeysuckle. Drive through a ghost town and wonder why it died. When's the last time you saw a country store's cured hams hanging from wires? How about a vintage Bull Durham tobacco ad on old brick? Author Tom Poland explores scenic back roads that lead to heirloom tomatoes, poke salad, restaurants that were once gas stations, overgrown ruins and other soulful relics.
