So if I was to draw a picture of my family on a rock, would that be okay? I won't claim ownership, nor would I "tag" the rock. I'll use one color and even do stick figures.
Editor's Note: I don't think people should be drawing on rocks today, I just find it interesting that one "old" picture on a rock is awesome and doing the same picture now would be a crime. Anyone know when it did become a crime? Aren't there some "good" ones out there that are less than 100 years old?
