Twice named an All-America City by the National Civic League, Sioux City, Iowa serves as a regional hub. Sioux City sits on the cusp of the westernmost reaches of the industrial Midwest.
Most of the rest of the United States between it and Denver is dominated by wide expanse of sparsely populated prairie. Sioux City is proud of its frontier history and you can find markings all over town dedicated to the western exploration done by Lewis and Clark.
