The back seat of Vern Stiller's silver Mercedes SR5 SUV is littered with maps, a hard hat, work gloves and an extra carton of Pall Mall cigarettes.
There are 180,000 miles on the odometer, with 80,000 more piling up yearly. He's driven 330 miles today and it's still early afternoon.
"That's a lot of ass time," said Stiller, 70. "I drive around, smoke cigarettes, drink coffee, talk smart and write checks."
His voice is pure gravel, his neck tan and weathered. You can't tell he's got an artificial leg under his bluejeans, a remnant of a busted ankle and frostbite from five decades working on oil fields in Texas, Oklahoma, Wyoming and now North Dakota.
"They call us land men," he said. "What we do is investigate, negotiate and argue."
As middle man between the oil companies and ranchers in western North Dakota, Stiller searches courthouses for titles and figures out who owns the mineral rights.
Then he greases the deal, acquiring rights of way easements for pipelines to move the oil and natural gas from this remote landscape to a world thirsting for fuel.
"I do love making deals," said Stiller.
