A crazed German in South America touring on a budget of one dollar a day. We never met him but those who did were changed forever by the experience.
He flew into New York, pedaled down to Central America, caught a boat past the Darien Gap and rolled through the Andes. After nearly three years of travel he had gone through about a thousand dollars.
While we have no intention of traveling so inexpensively, the idea opened my eyes to what was possible on a bike and got my heart beating faster.
