FILE - In this March 8, 2011 file photo, Cim Smyth from Big Lake, Alaska, comes into the Nikolai, Alaska, checkpoint during the Iditarod Trail Sled Dog Race. The 2012 race has its ceremonial start in Anchorage on Saturday, Mar. 3. A winter of heavy snow in Alaska is keeping trail breakers busy clearing the route of the 1,000-mile Iditarod Trail Sled Dog Race, but no one can remove other weather-related challenges like jumbled ice along the western coast and the heightened possibility of run-ins with grouchy moose.
