Catalina works to disguise the conspicuous Bushby as a drifter for his approach to the Darién Gap, the thick jungle between Colombia and Panama that is home to anacondas, crocs, jaguars, narcoterrorists, and FARC guerillas. "We dyed my hair and skin to make me look less like a gringo," he recalls. "But it started to fade quickly." Bushby floats along the Atrato River for four days, stuffing empty soda bottles into his vest for buoyancy, and camouflaging himself under a mat of branches. Boats carrying paramilitaries pass just feet from his head.
