Bim asked: "Is that like the Rebellious OutdoorsPeople who mysteriously disappeared after their brief and frantic appearance in March 2020?"
Yes, I do believe they might be exactly the same people. I remember going to my favorite little state park where I have been hiking regularly for years and being bowled over by the number of cars and people there. Normally I see a few folks out on the trails, but last Spring, for a brief period, it was actually verging on crowded. It's a small park that a lot of people don't bother with because it's really just trails and picnic tables, but boy, they sure found it last year. It didn't help any that state park admission was free for a while last year. So all these people who felt cooped up brought their kids and dogs and garbage to the state parks. They are gone now... things are back to normal.
