When it gets cold and deer want to bed all day, they like the sun on them the same as your cat or dog like to lay in the sun on a cold day. Southern exposure means sun. South facing slopes hold vegetation growth later in the year because of that sun also. In the winter, a South facing side of a hill will attract deer like a magnet, provided they have the right cover to feel safe. If it is very windy and cloudy, hunt the creekbottom trails. These depressions tend to shield them from the wind and they like that too. Food sources will be hit or miss because any nice buck will tend to still be wary from gun season, and probably won't travel far or become exposed during daylight. The rut is over as well and they have no want or reason to expose themselves anymore. Late season bucks seem to find the thickest place to bed during the day and will move around in that cover to browse during the day. After dark they will travel out and hit the edges for food. I don't know how they do it but they just seem to disappear and then reappear around March. Late season is tough, but fun nonetheless.
