Informal sales also occur across the country. One such example is in the Bismarck-Mandan area. Coinciding with the United Tribes International Pow-wow, it is a tradition for the weekend following Labor Day to be the area's biggest garage sale weekend due to the influx of visitors in the area. On any given year, total garage sales number at least 500, while Fargo, North Dakota surpasses Bismarck as the state's largest city. The only state event that is bigger is the North Dakota State Fair held in Minot, North Dakota, during the last week of July.
