C'mon I couldn't resist......A few thousand years from now, some great civilization will be wondering what this giant sandstone engraved rock represented. I think you should have put a time capsule inside with some old parts and stuff....and maybe a video from the Beagle. Oh, and maybe a jar of Bag Balm....it never goes bad. Anyway, no matter what you left your mark. Awesome job!mattbikeboy said:Stone..what. I don't think it exists!
