Che and Mike at the Plaza of the Revolution in Havana.
Che Guevara is everywhere in Cuba. He's a revered hero. His bones are in a mausoleum in Santa Clara and a museum is attached to the mausoleum. Guevara toppled a train outside of Santa Clara cutting off supplies to Batista's army. Three days later Fidel Castro took over the country. Visitors to the mausoleum/museum have to surrender their cameras so you're going to have to take my word for the following. Whatever else Che did or is reputed to do in story and song my lingering memory of the hero of the revolution is in a glass case in the museum dedicated to him. It's his Zippy Zither and the music for "Home on the Range."
On the way to Che and Fidel's mountain hideout high in the Sierra Maestra mountains above Santo Domingo.
