- Caraíba worked on a ranch in central Brazil until his mid-twenties. Like many working class Brazilians with little or no formal education, he knew he was going to work his whole life and have little to show for it. So he decided to try for something more, and struck out for the mines. Caraíba has done well for himself in the garimpo— millions of dollars of gold has passed through his hands, but he spent it andando, walking out and about, adventuring, and enjoying life. He loves the freedom of the mines.
