KRASNAYA POLYANA, Russia, Fog is the big winner on the ski hills today at the Sochi Olympics. The Olympic men's snowboardcross was postponed and a new date and time have not been set. The postponement came after officials scrubbed the seeding runs originally set for 10 a.m. local time. There are no medal events scheduled for the course Tuesday or Wednesday. Earlier, officials pushed back the men's 15-kilometer mass-start biathlon race from Sunday to today and again from today to Tuesday because of fog.
