"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. You are taken by surprise, because you know you haven’t wandered across the Texas-Mexico border. 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. "
