Donner Pass
I hiked from Donner Pass to a little past the road at Barker Pass and camped close to a bunch of people who were hiking the Tahoe rim trail that overlaps with the PCT for a stretch.
My first day of solo hiking went really well. I was able to go my own pace, check out a couple of spots and read about the Donner party's fateful winter trying to get over the pass. Its a pretty depressing story.
