Soar from North Dakota to South Dakota and explore two states born from one great territory. Explore natural wonders, manmade monuments, Wild West towns, and a really wild motorcycle rally. We celebrate the people inexorably linked to the land, including Lewis and Clark, Sacagawea, Teddy Roosevelt, John Jacob Astor, and Crazy Horse. And we reveal the milestones and landmarks that shaped the destinies of both states, from the Louisiana Purchase to the arrival of the railroad that put the Dakotas on the path to separate fates.
