I pedaled it saturday from LCF to Mt Wilson and it's pretty solid now. Not as nice as the road was new, and it needs some rockfall debris to be swept, but quite rideable. Then again, I almost descended via the Mt Lowe fire road because it was late afternoon and there's more sun there.
The center-line rumble strips are probably a bigger safety issue for the TOC than the road surface itself. They were pretty visible before, where they were cut into the fresh road. Now they're partially filled and some are more visible than others, and a hazard if you're anywhere near the center of the road with just two wheels. It looks like they painted indicators to recut them, but descending in a group with the center-line cutouts won't be fun-- worse than bots dots and reflectors for sure.
