I didn't get back on the trail that night. I've never been able to get a hitch after dark, so I've stopped trying. Instead I walked up the road to a park and slept on the ground in a thicket of trees and bushes, mostly out of sight.
It took three hours to get a hitch back to the trailhead, 2 hours longer than my previous longest wait, but I'm back on the JMT and 230 miles into a 270 mile trip.
The JMT requires only 219 miles or so, but I added a few detours. I haven't been in a rush to finish. Although, I am looking forward to seeing friends and family again. And, of course, starting the planning stages for the next adventure.
