“Do what you can, with what you have, where you are.”—Theodore Roosevelt
“After his humiliating election defeat in 1912, Roosevelt embarked on the most punishing physical challenge he could find, the first descent of an unmapped, treacherous, and extremely dangerous tributary of the Amazon. Together with his son Kermit and Brazil’s most famous explorer, Cândido Mariano da Silva Rondon, Roosevelt accomplished a feat so great that many at the time refused to believe it. In the process, he changed the map of the western hemisphere forever.
