winter fog

On the way back from the Augustow Forest just outside the village Lipsk encountered a very dense fog. Cars were moving very slowly, because visibility is constantly changing. Sometimes the visibility was several meters. It's unheard of, when the temperature. -9 deg. and clear sky. I think it's the influx of moist air from the west, where it has already started to thaw. Although I experienced a lot of winters, but such a phenomenon can not recall. We stopped to look at more closely and tried to make a few photos. The moon already rose above the horizon. Interesting experience at the end of the winter expedition to ski to the wilderness.
