Fancy driving to South America? Well the Pan American Hwy is not so Pan American: there is no road link between Central & South America. About 200km of inhospitable jungle, swamp and banditos separate Panama and Colombia. Known as the Darien Gap, Scotland bet the farm on colonizing the region in 1698; the ensuing financial ruin forced its amalgamation with England 9 years later. A National Geographic expedition actually did drive the Gap in 1961 but no one since.
