In this photo taken on Saturday, March 14, 2015, a Nenets boy sits on a sleigh as he attends the Reindeer Herder's Day holiday in the city of Nadym, in Yamal-Nenets Region, 2500 kilometers (about 1553 miles) northeast of Moscow, Russia. For the indigenous nomadic Nenets people, the Reindeer Herder's Day offers a chance to show their prowess in wrestling, high jumps and other traditional local sports, but, above all, reindeer races.
