ORG XMIT: IDCOE101 White ice crystals, known as radiation frost, decorate the flag on a mail box Wednesday, Jan. 21, 2009 in Coeur d'Alene, Idaho. The tiny spikes form on cold clear nights when radiation losses into the open skies cause objects to become colder than the surrounding air. (AP Photo/Coeur d'Alene Press, Jerome A.
