Sadly, restaurants and bars and social gatherings where people are not socially distanced are spreading the illness. No one has figured out how to eat and drink with a mask on so there is plenty of aerosol in the air. (mask off, drink, don't breathe, put it back on, right, don't breathe when your mask is off) Anyplace crowded is an issue. It will be interesting to see how schools function after 100 days. In most places here, for middle school and up, they are in a hybrid situation, no lunches, less than 50% of students so spacing is okay. The buildings were not built for 100% capacity and allowing for spacing.
I've been local mostly and mid-week so I rarely see anyone on the trail and since it's hardwoods, it's easy to get pretty far off the trail. I then wait a few moments as there is no reason to jump back in their wash. I have no idea on how some steep trails, how you move over for people passing from behind. (Flume Slide, when it gets steep, Knife Edge, the back side of Saddleback in the ADK, Huntington Ravine, you aren't getting six feet away from anyone on parts of these trails.)
