Still extremely cold today, as you may have noticed. The car said it was 1C but the ice forming around somebodies water cutoff manhole showed that it was probably colder in the wind and lso that they probably had a leak!

The skies were wonderfully clear and all the jets passing overhead were leaving long white trails behind them. Except one which crossed in a different direction to the others and was lower - this one was blowing smoke rings the whole way. I've had to crop quite a bit, just so you can pick out the rings in the blip.
