WILLISTON, ND - NOVEMBER 18: 'The Promised Land'. Williston, North Dakota November 13-18th, 2012. Scenes around the mammoth Walmart store in downtown Williston. It is claimed to be one of the biggest Walmart's in the country and often goods are sold so fast that the stores employee's don't even unpack the items for sale. Here a sign outside advertises for workers - $17 an hour is unheard of for this type of employment in other parts of the country.
