Parking lot vultures are bad, but parking lot spot holders are asking to be runned over. I almost ran over two that were "holding the spot" as I was turning to park. Good thing I never, ever go fast in parking lots.
As for the Scout troup leaders that tipped the rock? They should have gotten much stiffer penalties. What they did was vandalizing.
Vandalizing doesn't quite cover it - they didn't deface it by putting their names on it - they destroyed it as a natural wonder & turned it into some broken boulder that used to balance on another bit of rock in an amazing way but you can't tell anymore because it's all just bits (well, big bits, but broken bits) of rock.
The good news is that none of the kids in the troup got injured by the results of their macho idiocy.
The bad news is that there were not consequences to speak of to demonstrate why rolling balanced boulders off their balance point is a really, really bad idea.
Wyle E. Coyote would have been flattened at least twice by the boulder rolling over him, up a cliff face, and then back over him - while missing the Roadrunner entirely...but that would be in a Looney Toons cartoon. In real life, I'm amazed that the rock(s) didn't end up flattening something or spray broken bits into people.
