"You’re driving along a remote, dusty road, when suddenly you come upon a border patrol checkpoint. There, agents demand to see your identity papers, and search your car.

In fact, you’re quite sure of that, because you’re driving through rural Wisconsin countryside west of Green Bay. Even the Canadian border is more than 90 miles away. "
