I didn't wear my glasses this morning and my eyes were freezing (literally). The first time I pulled over I thought I just had something in my eye, though I couldn't find it and it just went away. Started up again and had something in my eye again almost immediately.
Then I put my glasses on
The ride home was pretty awesome I must say. We had a very light and fluffy snowfall taking place in the valley. Riding through a freshly coated landscape with those big flakes reflecting in my helmet light, cutting a virgin path in the trail.
Oh yes, it was a good night ride.
