Tiger Woods talks with Rory McIlroy as they wait to hit on the 12th hole during the final round of the Memorial golf tournament in Dublin, Ohio, on June 2. Few other American courses have the kind of history found at Merion. They have red wicker baskets, the symbol of the golf club, though its origins remain a mystery. Equally mysterious to Woods, McIlroy and the rest of the stars at the 113th US Open is Merion itself. Jay LaPrete / Associated Press
