Yesterday's killing frost

Fall is definitely here now. Yesterday morning we woke to a heavy frost and even the heat in the house kicked on. It was 29 degrees out. The leaves have been falling out of the trees at a much faster pace today. I love fall time but it can be a tad depressing once the trees are all bare. Here is one shot of the frost on the roof top where the sun hadn't melted it yet. The other is the evidence of the killing effect of the frost on the sunflower plants edging the patio.
