Decided to take my normal Innocent Path commute today to see what the conditions were like. Icy was the answer. Huge swathes of unrideable ice (that is until a chap coming the other way showed me his studded winter tyres). There are patches where the ice ran down the middle (where a compacted snow path had been created during the snow), but the longest of these was about 100-150 yards long.
I'll be sticking to the roads for the time being...
