Well, much of the trail is clear, or has a clear path through the icy bits. A few places, particularly between Gallows and Cedar, are icy from edge to edge, but they are short enough that you can either carefully navigate it or walk it.
One thing to be wary of is that it's frozen enough that the footprints and tire tracks are solid bumps and grooves, and they will jar you and cause your wheels to go in surprising directions if you're not careful.
There is a chance of more snow this evening (Thursday), but not a great chance, so it might get trickier.
Also today I spotted a small flock of juncos and a young fox ducking into the brush. A good ride in.
The first photo is taken near mile 10, between Gallows and Cedar, showing both clear and covered trail. The second is a closeup of the nature of the surface in such stretches.
