I don't like the look of it, but I have thought on it too, playing the 'Devils advocate' is it the follow on from what we call cave paintings now?
Ok you'll say cavemen painted images to tell the tale of the area, what to hunt, and area ownership e.c.t.
Is the difference so vast, youths going out in to the woods and marking out there 'turf', you see it in every city, and it's all in a language we don't understand.
Now in a thousand years will outdoors people find these images and try work out what they all mean, I work with a number of kids who go out on motorbikes, have fires, and drink beers, and leave places looking awful, we've all seen it and will again. We try and get them to understand the damage they are doing and you'd be surprised just how well it works - only trouble is each year another batch spring up.
