Iowa is located in the Midwestern United States, an area often referred to as the “American Heartland”. Started as a French colony of New France, today Iowa is often known as the “Food Capital of the World” because of her agriculture’s historical importance. However, in the latter half of the 20th century, Iowa’s agricultural economy transitioned to a diversified economy of advanced manufacturing, processing, financial services, and green energy production. Iowa is bordered by the Mississippi River on the east; the Missouri River and the Big Sioux River on the west. Like most of the Midwest, Iowa has a humid continental climate with extremes of both heat and cold. Tourism is not a big business in Iowa, but a number of visitors is increasing every year and today there are quite a few spa establishments that offers an opportunity for a healthy vacation.
