Dallas Seavey won his fourth Iditarod race today, completing the 1,000-mile trek from Anchorage to Nome Alaska in a record 8 days, 11 hours, 20 minutes, and 16 seconds. This year’s race was marred with tragedy when a snowmobile driver was charged with intentionally running his machine into two sled dog teams, killing one dog and injuring others. The race is a remaking of the freight route to Nome and pays tribute to the role sled dogs played in the settlement of Alaska. -- By Lloyd Young
