This study found that snowmobiling is a popular activity in South Dakota, and is associated with substantial spending each year. One area, the Black Hills, is a destination that draws resident and non-resident users, is highly-rated by all users, and generates substantial economic impact. The East River area, although more extensive, is not a destination, has lower user satisfaction, and generates less economic impact.
