I would just ignore the "opinoinated" and "harsh" remarks about this. The fact is whether or not it is "graffiti", it is an interesting find, and you should not give up on it just because some don't have a good imagination. (not saying you are using you imagination when it comes to this rock!) What I guess I mean is, people who are always so absolute in what they "think" they know about something, when they really know nothing, simply will not find as much treasure as those of us who might be labeled as "dreamers". I am a person that many have called (derogatoraly) a "dreamer", but I find treasure. And I have found some amazing stuff,(at least amazing to me) and I am sure you are the same type of person, and hope you all the best in whatever venture you take! (Sometimes comments people make on here annoy the crap out of me, but then I realize how little they really know about what we "finders" do!) Anyhow, have fun on this adventure, and I'll be watching this thread to see if anything "pans out"!!!
