Between which two countries is the heaviest fortified border?

North Korea and South Korea. "SEOUL, South Korea -- Near the Demilitarized Zone, where grim- faced North Korean and South Korean soldiers eyeball each other's every move, children giggle on a roller-coaster ride. A small amusement park called Peace Land is one of the first things visitors see upon passing a military checkpoint at the DMZ, one of Seoul's most popular tourist attractions. Cartoonish plastic South Korean MPs stand sentry outside a theater and museum. A South Korean tour guide told us -- six American reporters participating in the 2007 Korea-U.S. Journalism Exchange last month - - the 2.4-mile wide, 155-mile-long swath of ground dividing the two countries since July 1953 is now a symbol of peace and unification rather than a partition. The heavily fortified border, in fact the world's heaviest, suggests otherwise." Source: http://findarticles.com/p/articles/mi_qn4188/is_20070518/ai_n19169036 Jun 27 08, 3:45 PM
