"Missouri is called "The Show-Me State," because that was the winner of the Dumbest State Nickname Contest, narrowly edging out "The Nanny Nanny Boo Boo State." The largest city is St. Louis, which features a 630-foot-tall stainless-steel arch, a monument to the early pioneers who came west with nothing but their wagons, their guns, their dreams, and their 630-foot-tall stainless-steel arches. Visitors may ride to the top of the arch, high above the Missouri River, where they will experience the thrill of wanting really badly to get back down on the ground. At least that was how we felt. You'll also want to go to visit Hannibal, the boyhood home of Samuel Clemens, who grew up, adopted a pen name, and became one of Missouri's, and America's, most beloved characters: Harry Truman. Missouri is also dynamic."
