I hope everyone had a good Christmas. I was working, but managed to get to a family party at 2300 on Christmas night. They had a big plate of turkey waiting for me.

I spent the week before Christmas driving up and down to Wales, a round trip from my home in London of about 350 miles. Last Friday, the whole of the southern part of Britain was shrouded in fog, and when I got back to London it was like driving through one of the old fashioned pea-soupers, which we thought we'd seen the back of after the series of Clean Air Acts which began in Britain in 1956. The fog even smelled foul, and it was a horrible green colour. Most unpleasant to drive in.
