My last chance to be a boy

"Perhaps because of his love of birds, Teddy Roosevelt went to South America five years after leaving the White House. His adventures down a southern tributary of the Amazon appeared in Through the Brazilian wilderness (1914). In 1992, Ornig, Roosevelt's great-grandson, retraced the route and described his experiences in this version of the President's trip. Interesting for field geographers who want to know just how tough it used to be to travel down the Amazon"--Handbook of Latin American Studies, v. 57.
