Painted images of Ernesto "Che" Guevara stare from a pock-marked wall in La Higuera, Bolivia, Saturday, Nov. 13, 2004. Guevara was captured by the Bolivian army in 1967 in a nearby valley and executed in La Higuera days later. Guevara and fellow communist guerillas were attempting to launch a continent-wide revolution modeled on Guevara's success in Cuba in the late 1950s. The Bolivian government recently began promoting the area where he fought, was captured, killed and burried for 30 years as the "Ruta del Che," or Che's Route.
