This is the season when north-bound PCT thru-hikers start out from the Mexican border. They're facing issues similar to what we've been discussing here. The Pacific Crest Trail Association is recommending not doing the trail this season, and getting off if you're on it. Most hikers are taking the advice. Estimates are that 100 to 200 hikers are still going for it. About 10% of the numbers that would be on the early parts of the trail in a "normal" year.
Imagine planning for months (even years) to do the trail and then this happens.
And BTW, I'm not sure I agree with the Association's advice. Yes, one has to leave the trail to get food and the like. But so do people at home. Most of the time one would be well and truly "socially distant."
Hard call.
