We went to the Iditarod Trail Headquarters in Wasilla. Saw and excellent video on the racing, history and the dogs. The Iditarod Trail had its beginnings as a mail and supply route from the coastal towns of Seward and Knik to the interior mining camps. On the first Saturday in March, mushers line out their dog teams in downtown Anchorage for their turn to start the 'Last Great Race on Earth', the Iditarod which is 1100 miles ending in Nome.
