Very foggy this morning. Went for a run before work. Had a near catastrophe when I tripped on an uneven piece of sidewalk I missed in the fog and dark, even though I run with a light. Closest I've been to going face first into the concrete in a long, long time. Somehow I managed to stay on my feet, although the awkward flailing of my arms and legs tweaked the muscles and joint of my right knee a bit. Thankfully I pushed through it and the pain settled down after about 1/4 mile.

Still foggy for the ride to work. Took the road bike even though there's a 20% chance of rain. Temp was in the mid-40s and the wind was light. Actually was a fairly pleasant ride.
