The oldest major city and perhaps the most cosmopolitan one in North Dakota, Grand Forks is home to the state's leading university and a major Air Force base. The North Dakota Museum of Arts and Chester Fritz Auditorium highlight the arts community of the state's second-largest city. The Center for Fine Arts and local galleries add to the cultural mix. The campus of the University of North Dakota in Grand Forks offers both a wide variety of activities and places for quiet contemplation. Grand Forks has a water-slide complex with a miniature golf course, terrific riverside city parks and 63 holes of great golf, including the truly outstanding Grand Forks Country Club. Summer activities offer fun for all during Summerthing, Catfish Days, Heritage Days and Friends and Neighbors Day.
