I had a lovely ride home. Snow tyres meant I went to play on the cycle path rather than my usual road route. I passed a few miserable looking cyclists pushing their bikes home in the not very deep snow. It was lovely; I reacquainted myself with the handling and experimented a few times with trying to lose rear wheel traction standing on the pedals. It can be done, but you don't completely lose traction as the studs dig in once the wheel starts to slip, I think. And if you stay sat down there is loads of traction, and going up steep slopes was easy.
Great fun, and snow tyres turn riding in snow from a chore to a giggle.
