Iditarod down to final push - winner expected overnight

The race is on in the Iditarod as the two front runners begin the final 77 miles to Nome.  A winner is expected in early tomorrow morning.  Lance Mackey left the White Mountain checkpoint at 4:53 this afternoon, and Jeff King will follow him out nearly an hour later at 5:50.  The next group of mushers vying for third are more than four hours behind, giving the two leaders a wide berth.  Ramey Smith, Ken Anderson, Hans Gatt and Martin Buser are all taking their mandatory 8 hour rests in White Mountain in a tightly packed group. They'll leave the checkpoint within a half hour of each other at  11:44 tonight.Libby Casey, KUAC - White Mountain
