Beyond So Cal the towns start to get further apart. There's a segment in Nor Cal where you get to stay with people in their homes and be fed nearly every other day for a couple weeks. My mom is one of them. She loves meeting hikers.
Oregon and Washington have fewer towns along the way. About every 4 days or so there's some kind of place to stay but sometimes you are lucky to get a shower and laundry and sleep in your tent somewhere.
Here's a list of pct resupply points. Not sure how much sense it'll make but you can see the possible towns along the way.

I would totally hike again, but now that I have a decent job, I don't want to leave it for a lengthy trek. I was thinking of going with my friend Shroomer (a culinary mushroom expert) to Glacier National park next summer. He said that was the prettiest section of the Continental Divide. He wants to go back to see it again a little slower with a hiking friend from Japan. That would be all wilderness.
