It's all over in Sochi. With a nod to Russia's Olympic past and 900 children carrying small flames, a giant bear huffed and puffed and blew out the Olympic flame of the Winter Games. Moments later, the giant cauldron outside the Olympic Stadium was extinguished, marking the end of the 17-day games. Russia won the most medals with 33. The U.S. was second with 28.
