In the middle of October we hail Richard Nathan, a British adventurer who would be right at home with the likes of Robinson Crusoe or Dr. Livingstone. But his wilderness isn't to be found in the midst of far-away continents nor deep in a romantic past. His wilderness is North America and some of its longest-inhabited regions. His time is now. Mr. Nathan took a walk from Canada to Mexico. His adventure just might change the way you think about our country. Take this journey with Richard Nathan.
