First snowstorm of the season

First snowstorm of the season arrived today, by late afternoon the was close 40cm of snow on the ground.  Because of the heavy snow  that was falling and  the wind making for poor visibility I chose to shoot in manual focus mode and 200 ISO.   I keep a dry cloth handy to wipe the snow off my camera, even if i'm shooting with a weather resistant  Canon L lens and EOS 1D MkII camera body.  Better safe than sorry.
