Mullen, Nebraska, sits deep in the Sandhills, four-plus hours from any major airport, in a country of grass-covered dunes that roll away in every direction like a sea that forgot to move. For decades the golf business built where the people were. Then, in 1995, a course opened here, in the middle of all that emptiness, and proved that a faraway course on spectacular land could work. Much of the credit belongs to Dick Youngscap, the developer who pushed what sounded like a crazy idea: take golf to a small town at the edge of nowhere. The course itself belongs to Bill Coore and Ben Crenshaw, two men drawn together by the Golden Age of architecture and a shared conviction that traditional, strategic golf is the most rewarding kind. Sand Hills placed this remote and seemingly desolate region firmly on the golfing map. It was a field of dreams moment, and it changed the trajectory of golf course architecture, helping lead a rebirth of classic design across the country. What makes the story so appealing is how little was forced. Sand Hills was built on a shoestring budget, and Coore and Crenshaw did very little earthmoving. On most properties the problem is squeezing eighteen holes out of stubborn ground. Here the problem was choosing. Near a staircase in the clubhouse is a constellation map of their routing ideas, more than 130 potential holes scattered in and around the valley where the course now lies. Standing in front of it, you sense the abundance they faced, and the restraint it took to settle on just eighteen. The one green that demanded considerable shaping was at the par-4 fourth, which benches into a big sand dune and falls off hard on the right. Even the changes have been small and deliberate. The 12th opened without a greenside bunker, and one was added a year later to enhance the strategy of the hole. The scale invites ambition. Fairways are wide and generous, winding beside huge dunes, and it is tempting to open your shoulders and swing freely. That temptation is the trap. The bunkers are crater-like, and avoiding them takes either an extremely good golfer or a very lucky one. The width is not a gift so much as a question about where, exactly, you mean to go. Wind is the other partner in the conversation. It can whip across these plains with great force, but it comes from no prevailing direction, so the designers took care that the holes would be playable in every condition. Fairways are sensibly spacious, and target areas are mostly open, encouraging the ball to chase in along the ground. The greens wander through an astonishing range of settings, pitched in hollows, set atop plateaus, built beside exposed dunes, and their putting slopes are just as remarkably varied. All of this belongs to very few people. Sand Hills has only a small number of members, and the course is closed for eight months of every year, so overplayed it is certainly not. Surely each member keeps another club somewhere else and carries this one like a secret season, a few months of grass and sand and sky in the middle of Nebraska. It is a course worth studying for anyone who hopes to design golf. More than that, it is a course worth longing for, a reminder that remarkable ground can wait far from where anyone thought to look.
