Met a few other hikers in Lake Morena. This is the first organized campground along the PCT, and it mostly serves car campers, but with a designated area for hikers.
Two guys camped in the tent area with me had already been here for a couple days. I can't remember their names, but one of them was from Australia and was already sidelined with bad blisters. This is only 20 miles into the trail. I don't recall seeing him again, but hopefully his hike didn't come to an end here at Lake Morena.
Amusingly, I saw these three crazy people inflating a big queen size air mattress and then wrestling it into their large car camping tent. Little did I know then...
