I think I understand the joke, but I've seen things from this point of view as well. Something happened during and after pandemic lockdowns that has led to absolutely unprecedented numbers of people going out and hiking what were previously really quiet trails. It was already tough maintaining them before, now you've got tons of people who don't bother to know the norms or understood rules of the parks.

Several parks near me have had to institute an admittance/ticketing program with reservations made a month in advance just to enter the trailhead lot because they're so overrun with people now. It's great that people are outside and enjoying a public resource, but maybe it's just a few too many people all at once?
