The Toxic Twins and Freezing Fog

So its been pretty cold lately......scooping ice off the water cold. But the sun has been out, somewhat warming us up.  Xmas Day we gave everyone a xmas feed. Boxing Day we moved the big ponies into the 4-Acre field....Our Winter grazing. The 3 smaller ponies are grazing off the whole of the Hill Field plus having a lot of Hay. 
We wanted to go for a xmas day ride........but Jo and I are The Toxic Twins. Jo has a chest infection and is swigging anti-biotics followed by a Steroid Chaser, and I have my annual Xmas Cold.  Full of snot and as weak as a new-born.
So just the basic care is enough at the moment. Normal people would be in bed.
But we are not normal.....we have horses.  They need looking after, no matter what.  As I always say 'Fresh Air never killed anyone'......except maybe Scott of The Antarctic.....and errr people dying of exposure, hypothermia....Ok pass me a spade!
And so today we had freezing fog. The first time i have felt really cold.  Numb fingers an all.  Checking the weather app (rather than going by feel), it said -3.
We upgraded Pollys rug, being old and somewhat bad-tempered with the Shetlands.  Armed with thicker rugs for the big ponies we found the more sheltered 4-Acre field much warmer.  The ponies all felt warm enough in just lightweight macs, so we left them happily munching on the still longish grass and went home to spend the afternoon on our respective sofas, swaddled in blankets and dogs.
