How does this work, practically, since it’s so notorious? Is there a queue of dudes waiting to get access to this “private” tree?

I wonder if it has been ruined by becoming well known.

It is sort of funny—based on the Wikipedia they put up notices to stop people from having sex there, which didn’t work. They should have advertised it instead, maybe, the surest way of ruining something niche is to let everybody know about it.
