Every year, we see hundreds, thousands, and, soon, even millions of people following the same steps that Lewis & Clark traveled over 200 years ago. 
We see people reliving the journey by car, RV, boat, motorcycle, canoe and bicycle. Some prefer the comforts of home offered by AmericInn & restaurants, while others pitch a tent and cook meals over a fire each night.
Whatever your means of traveling and living during your own Lewis & Clark adventure, the Chamberlain-Oacoma area offers something to help make your travels worth writing home about. 
Visit the newly expanded Lewis & Clark Interpretive Center at the Chamberlain I-90 rest area between exits 265 and 263. The center features interpretive displays recreating the landmark journey. Also, view the wide expanse of the Missouri River from a 55-foot replica keelboat
