On day two of my trip, I travelled 250 miles across the state of Missouri. It is in the Midwest Region of the United States. See the famous Gateway Arch; cross the Mississippi and Missouri rivers; find out where Dred Scott, a slave from Virginia, sued for his freedom; visit the National Frontier Trails Museum, and see where the pioneers set off on their journeys west; discover the place where Lewis and Clark began their famous expedition! Come on, let’s go trekkin’!
