National Geographic Explorer Paul Salopek tells host Carolyn Beeler about his first stop after having walked through the Middle East. On Cyprus, he found beaches with baking European tourists, a busy port city and a checkerboard of olive groves and yellow hay fields. But he also found the vestigial border line that divides the island's Greek and Turkish communities, and walked through an abandoned tourist city, a relic of a border war that has never been fully resolved.
