If you ever plan to travel between North America and South America, you must consider that there is road.Ten hours southeast of the Panama Canal, the Pan-American Highway penetrates the jungle, shrivels into a footpath and dies. The highway resurrects in Colombia, ather continent. But the land between the two countries is a vast and primitive realm. On a map the two ends of the highway appear as two slivers of life, separated by the unkwn.Filling this void is a rugged wilderness kwn as the Darien Rainforest. Because the Darien hinders all contact by land between North America and South America, it has earned the name the Darien Gap. Yet most travelers never encounter the Darien Gap. When they go to South America they fly or perhaps take a boat. I decided to cross the Darien overland, traversing from Panama to Colombia by foot and riverboat.
