On his 43rd birthday, Dick Conant, a golden boy who never quite grew up as those around him expected, stepped into a homemade boat to embark on a journey despite a gathering snowstorm. It was the beginning of an all-consuming odyssey by an unconventional man into the watery arteries of America, a journey to the unreported margins of society. He was to spend the next twenty years canoeing thousands of miles of rivers and their innumerable smaller tributaries, from one end of the country to the other. And then, in 2014, he disappeared. Riverman is the story of a restless soul who was as troubled as he was charismatic, a contemporary folk hero who slips the moorings of ordinary civilised life to tap into what Thoreau called ‘a yearning toward all wildness.’ It is also a riveting portrait of an America we rarely see: a nation of unconventional characters, small river towns, and long forgotten waterways.
