200 years ago, Lewis and Clark charted the rivers of what is now Northwestern America. In the 21st Century, travelers seek the same mountains and rivers to get away from their crowded urban lives. Rick discusses the basics of back-country river rafting with Peter Grub, who runs a river adventure company in Coeur d'Alene, Idaho. We'll also chat with Julian Smith about the Four Corners area of the US Desert Southwest, talk with listeners about travel plans and challenges, and take a tour of Montreal with a listener who lives there.
