Actually I forgot that I got word from the planners that the up coming SCA crews that will be working the PCT for the next 6 months have at least one 10 day hitch doing mostly tread work on the section of PCT from Long Valley Loop Road down into Rockhouse Basin. You can go for a single day or all of it.
Just keep your eye on the schedule as they should be posting the SCA crews within the next week or so.
I remember hiking that stretch in 05 (how can it be that long???) I vaguely remember thinking that was an old fire road.
