Ya it did! Not only did it frost, all the horses water buckets hanging on the fences had a skim of ice. I expected frost but not frozen water pails. No wind but I had to go back in to get a coat on over the coveralls. I didn't look at the thermometer when I first went out. The sun is shinning bright so the white grass will go away when it gets out of the shade. 36º when I just came in at nine AM. Worked on fence all afternoon yesterday on my hands and knees and will get back at it this afternoon and move horses around for winter at chore time. That would be if I get the fence tight enough to hold the two escape artistes. Probly spread a coupla loads of horse apples.
