Got a few cm of snow last night. My bike doesn't have studded tires, just knobbies but they was not sufficient to make much headway (more sideways movement than forward) so I turned around after about 50m/yd, put the bike back in the garage and walked in (late, shhhhh!!).

I'll try again on Wednesday too but we're not expecting additional snow, just mild for the next couple of days (+1C today, +2C tomorrow), then down again to cold for Wednesday/Thursday (-12C/0F highs, -23C/-9F lows) when the path conditions will be better for my bike's tires.
