Pickled Beets and Sleet this evening

Yesterday was a wonderful day....​I had a new Sump Pump installed, no water in the basement now. and I rearranged the perches in the chicken house and the young girls are much happier. The sheep like to lean against the chicken fence and the chickens come and pick stuff out of their coats.
This evening I pickled some golden and red beets. I went out to walk the dog and it was sleeting..........it is 37 degrees and it is October 17th......what's the deal with that?
