I respectfully disagree. Did you see the photos of the vehicles parked all along the road at Mountain Crossings?
per the ATC...
“In a time when social distancing is necessary to minimize the spread and contraction of a dangerous virus, many have escaped to nature seeking isolation and unpopulated spaces. On the A.T., however, what they’ve found are trailhead parking lots exceeding their maximum capacities, shelters full of overnight hikers, day hikers using picnic tables and privies, and group trips continuing as planned. Popular spots along the Trail like Blood Mountain in Georgia, the McAfee Knob area in Virginia, and Annapolis Rocks in Maryland have seen day use reach record-breaking levels. Cars line the highways leading to popular day-hiking spots on the Trail. Hiking the A.T. has become, in other words, the opposite of social distancing. “
I believe it’s only a matter of time before the state and federal government close their respective parks.
If you pay attention to the simplest precautions regarding distance, what you handle, touching your face, and washing your hands I don't see how you can "feel" more vulnerable than in a relatively enclosed space where, much of the time, you can't maintain the recommended distance. Now, I wouldn't argue if you said you observed most of them blithely ignoring the rules; I see that myself, and I'm baffled by it. But I see no science-based reason why you can't stay safe on the trail just because there are lots of people out there.
