It has been effing cold the past couple of mornings (low 30's) and in some of the large field near my house this has caused a cool low-fog phenomenon. Some of the fog/mist is frozen on the grass.. I caught a quick cell phone picture of it yesterday morning. This is about a mile from my house and it's not uncommon to see 100 or so cows in the far pasture.
