For years, the Bakken has been known to be a major oil and gas hub and it is the third largest U.S. shale oil field, behind the Permian Basin and Eagle Ford, in Texas. Primarily located in North Dakota, it also runs through Montana and two Canadian provinces – Manitoba and Saskatchewan. Because of the oil play there, McDonalds’ workers have been known to make upwards of $20 per hour to accommodate the high numbers of clientele.
