I suppose I was a crazy going in on the bike but don't go past Fairfield hall.
Journey in was OK missed out the usual side roads and kept to the mains with no problems.
Coming home was a different matter, kept to the main roads again, I usally follow Andrew G's Dulwich route but glad I stayed clear. If you kept in the car tyre tracks it was OK, but after a while the traffic was at a standstill and ended up walking for a bit. The pavements were fine though nice crunchy snow. Streatham Common was fun, could just let go, then more fun across Mitcham common, made the slog worthwhile. If it freezes though it will be lethal.
