Back on the PCT after 17 years! I did about a half mile in the 90s near Mountain Center. Tag on about 12 mi today and I should be to 1% in 20 years. Of course I hiked one of the nicer southern portions going around Big Bear so I haven't a clue on the mundane miles.
I didn't have much planned. Instead I relied on the national PCT to be well trodden and signed. It is definitely well used and manicured. A slight guessing game when it crosses bike paths. Yet generally within a hundred yards is a sign declaring no bikes or motorized vehicles.
No hikers passed until I reached Cougar Crest, just picnic'rs and teens near road crossings. The half mile before CC is pretty much world class hiking. Yes I've been to Antarctica... peanut gallery. Gnarly juniper overlooking the lake with the ski slopes dwarfed by the alpine cap of Mt Gorgonio, accented by puffy clouds.
Not much flow. Nice clear pool, enough to filter for a small army.
