Studded Nokians = Worth their weight in gold.

We had some freezing rain this afternoon, and by the time I left work, the MUP was a 5-mile ribbon of glare ice. (Except for the bits that had snow on them.)

I got down from the saddle a couple of times and let my foot drag on the ground. No traction whatsoever.

I came upon a young woman who was walking. Her feet were sliding all over the place. She heard my studs crackling on the ice, turned to see what I was, and said, "How do you ride a bicycle on this ice?!" I said, "Studded snow tires!"
