The Corps of Discovery, better known as the Lewis and Clark Expedition, travelled up the Missouri River across Montana, Idaho, and Washington, to the Pacific Ocean and back in one of America's best-known and least understood adventures. What did the Corps of Discovery actually accomplish? What did the expedition mean to Americans at the time and later? What specific activities were important then that are less important now? How has technology affected such things as weapons, travel, food, and communication? Participants engage in a lively discussion of what the journey was actually like and what its successes and failures were and are.
