Rode Mahlon yesterday with Nokians on. Snow was deeper than I thought, with a really shifty base underneath. Challenging but a great cardio workout to say the least. Toes got prety frosty, feet hit the snow at the bottom of each pedal stroke. Took quite a few laps around the cleared off area of Saffin Pond ice to finish out the ride. I didn't see another set of bike tracks at all.
