Apart from a few fanatics who sometimes turned up at midnight, the landmen would begin arriving at the courthouse around 6 a.m. In the dead of winter, it would still be dark and often 20 or 30 below zero, and because the courthouse didn’t open until 7:30, the landmen would leave their briefcases outside the entrance, on the steps, in the order they arrived. And then they would go back to their cars and trucks to wait with the engines running, their faces wreathed in coffee steam. Sometimes there were more than 20 briefcases filed on the courthouse steps. The former landman who told me this — Brent Brannan, now director of the North Dakota Oil and Gas Research Program — said he sometimes thought he could see the whole boom in that one image, briefcases waiting for the day to start, and it killed him a little that he never took a picture.
