Iowa

"Iowa is a U.S. state in the Midwestern United States, a region sometimes called the "American Heartland". Iowa is bordered by the Mississippi River on the east and the Missouri River and the Big Sioux River on the west; it is the only U.S. state whose eastern and western borders are formed entirely by rivers. Iowa is bordered by Wisconsin and Illinois to the east, Missouri to the south, Nebraska and South Dakota to the west, and Minnesota to the north. ... Its capital and largest city is Des Moines."
