On Kern's hunt, Tommy Roberts helps runs the show. A good-natured Texan with a quick smile beneath a dark mustache, Roberts has participated in the Nazareth community hunt for years, and he shows up with a plan. By the side of the road he gathers his hunters around a black pickup and sketches out the upcoming push on a dusty rear quarter-panel, drawing half-moons and hash marks with his fingertip. His son, Matt, leans over and laughs. "Yesterday, he let us have it because we didn't have enough line discipline," he says. "But he knows what he's doing. Walk slow, zigzag, and pause. It makes a big difference."
