Our roads seemed to be covered in a thick layer of ice with a centimetre of slush on top this morning. It was slippier than a slippery thing covered in slip.
The commute had to be re-routed to find the gritted roads since the back wheel was just sliding out from underneath me, and the cars were going sideways. Tim had an off, as did another cyclist he encountered, and then he met a car driver sitting quietly by the side of the road and waiting for the nerves to subside.
Would have been fun on an MTB, but I've no lights suitable for off-roading.
I shall be taking the prudent route home also. Snow is fun, but that stuff is more dangerous than the stuff we had in the Alps! I've seen at least one car resorting to snow chains to get their car out of their ungritted road.
