Guevara's parents, who knew that their son was both a severe asthmatic and a medical student close to completing his studies. However, Granado, himself a doctor, assuaged their concerns by guaranteeing that Guevara would return to finish his degree (which he ultimately did). The first stop: Miramar, Argentina, a small resort where Guevara's girlfriend, Chichina, was spending the summer with her upper-class family. Two days stretched into eight, and upon leaving, Chichina gave Guevara a gold bracelet. The two men crossed into Chile on February 14. At one point they introduced themselves as internationally renowned leprosy experts to a local newspaper, which wrote a glowing story about them. The travelers later used the press clipping as a way to score meals and other favors with locals along the way. In reference to his experience in Chile, Guevara also writes: "The most important effort that needs to be done is to get rid of the uncomfortable 'Yankee-friend'. It is especially at this moment an immense task, because of the great amount of dollars they have invested here and the convenience of using economical pressure whenever they believe their interests are being threatened." Unable to get a boat to Easter Island as they intended, they headed north, where Guevara's political consciousness began to stir as he and Granado moved into mining country. They visited Chuquicamata copper mine, the world's largest open-pit mine and the primary source of Chile's wealth. While getting a tour of the mine he asked how many men died in its creation. At the time it was run by U.S. mining monopolies of Anaconda and Kennecott and thus was viewed by many as a symbol of "imperialist gringo domination". A meeting with a homeless communist couple in search of mining work made a particularly strong impression on Guevara, who wrote: "By the light of the single candle ... the contracted features of the worker gave off a mysterious and tragic air ... the couple, frozen stiff in the desert night, hugging one another, were a live representation of the proletariat of any part of the world." In reference to the oppression against the Communist party in Chile, which at the time was outlawed, Guevara said: "It's a great pity, that they repress people like this. Apart from whether collectivism, the 'communist vermin', is a danger to decent life, the communism gnawing at his entrails was no more than a
