Bought a mirror to put on my bike. Now I can see cars coming from behind.
Since the roads are clear and we don't have any significant snow in the forecast, I switched back to the Schwalbe Marathon tires. Oooh, they roll nice! Quite a bit less effort than the studded tires.
I also put new brake pads on all around. I noticed the old pads were severely worn when I went to adjust the brakes. The sand the highway dept puts on the road must be very abrasive to the pads (and probably the rims, too). I cleaned the wheels up nicely as well.
