As far as hitching goes, I would imagine that doing so requires at least a little bit more patience than normal. But that said, I was in and around Lone Pine for about a week at the beginning of July and saw plenty of people getting rides the same, socially distant way--pickup trucks.
I picked up a hiker and his dog on Friday as he was hiking down from Horseshoe Meadow to Lone Pine. I recognized him from the campground.
I have a Ford Ranger with a camper shell.
The first thing I asked him was how much water he had (a gallon). On the ride down he pointed out where to find water and how to get it from that source. He obviously had experience doing just that.
Turns out this guy had been doing the PCT NOBO from the Mexican border (skipping the desert) but did not know that dogs were not allowed in Sequoia Kings Canyon National Park so he exited. This dude looked homeless, but he wasn't. The trail was his home.
