Well, that was fun. It's taken me about an hour and a half to get from SE21 to SE13, right through the middle of the snow. Solid traffic, cars and vans getting stuck uphill, the usual joy. Maybe I could have ridden faster, but it was all very pretty.
By the time I reached Ladywell it was thawing rapidly: the warmest air we've had all week. Until it freezes again the roads should move more freely.
A roll of thunder came over from about Woolwich. I don't know what that was about.
