 There was people that traded mineral acres for 10 cents an acre, and they didn't know what they were doing. Some farms retained all or part of their mineral rights. Others did not.

While farming is still a very important part of this town's present and future, the oil industry also drives the economy. That part of the story, next time as we travel the countryside in Tioga, North Dakota, I'm Andrew McRae.
