Central Park can be a forbidding place on winter evenings.
The shadows, the stillness, the cold, stinging air. But that's not how Hakan Durantas sees it. In fact, on those nights when breaths blossom and bare hands numb in the icy air, there is no place he would rather be. On this night, Durantas and his younger partner, James Cleary, are on West Park Drive about halfway around the six miles of roadway that circle the inside of the 843-acre park in the heart of Manhattan. The two of them run in tandem, with Cleary lagging a little off Durantas' right shoulder.
