Karl Bushby's Walk Around the World: Detained in Panama, 2001

On the Panamanian side of the Darién Gap, Bushby is nabbed for running the border. The jail is "scary," he says, "a big yard with huge guys working out with chunks of concrete and a pit in the middle for a bathroom." The inmates call Bushby "El Caminante" – the Walker. When one breaks the prison's work saw, Bushby gives him a tiny wire saw, a survival tool that he'd sewn into his collar. Guards soon separate him from the others. After three weeks, he leverages diary entries containing info on guerilla positioning within the Darién Gap to secure his release.
