The famous Iditarod sled dog race is undergoing permanent changes as organizers cope with urban sprawl and a warming climate. For the ceremonial start to the competition on Mar. 1, racers will travel 11 miles instead of the traditional 18 miles. The race itself will kick off Mar. 2 from Willow, Alaska, 30 miles north of the traditional starting town of Wasilla. Says Stan Hooley of the Iditarod Trail Committee, "A lot of development in the area makes [Wasilla] less desirable, and there have been less-than-winter conditions." And that's no way to race a sled, dawg.
