With its rolling hills and endless prairie land, North Dakota is a state that seems to have changed little since the time that Native Americans first inhabited it. The state is not densely populated; Fargo, the state's biggest city, has just over 100,000 people. However, the state has seen a recent economic surge with the development of new oil extraction techniques. Despite the state's sparse population, there's plenty to see and do in North Dakota, ranging from cultural festivals to art exhibits.
