PAJU, GYEONGGI, SOUTH KOREA: South Korean tourists take selfies with a smart phone at Dora Observatory, on the edge of the DMZ. North Korea will be in the background of their selfie. Tourism to the Korean DeMilitarized Zone (DMZ) has increased as the pace of talks between South Korea, North Korea and the United States has increased. Some tours are sold out days in advance.
