The 29th Frostbite Road Race
YOKOTA AIR BASE, Japan -- A runner dressed as a Tiger participates in the 29th Annual Frostbite Race, Jan. 17. Some runners wore tiger costumes, because 2010 is the Chinese zodiac sign of the Tiger. Some of the 9,000 runners who participated chose to wear costumes, because it has become an established custom every year. (U.S. Air Force photo/Osakabe Yasuo)
