A family from the Embera tribe ride in a canoe with their produce to be sold on a market on the Tupiza river in Darien February 17, 2010. Drug-running Colombian rebels are using the dense, lawless jungle joining North and South America to smuggle cocaine past sea patrols, creating a new troublespot in the continent's drug war.
