Well looks like Im spending my afternoon in Biggin Hill then lol! And it seems your right Mr Erith, I don't think theres anywhere thats been worst off for snow this winter in the south east than our little area of kent/se London, and possibly areas just the over side of the Thames.
Referring back to my previous post about Central London getting more snow than us this winter, the snow event on 13th January is the best example. I left Dartford for work in the morning and a bout an inch of snow, every stop on the way in to central London on the train appeared to have a little more snow. Bexleyheath more than Dartford, Lewisham more than Bex,heath and so on at Charing Cross I saw the most around 3inches I'd guess!! So I'm guessing areas in north and west London had even more!!
