You're right about not accepting any opinion other than my own. Perfectly. But they aren't going to get there - it's taboo land - and why would they need me there anyway ? It's you that's wasting my time (but I can accept it's part of the process of getting this place recognised).
SL, best of luck with getting them recognised.
You could always get the archaeo's that FourWinds mentioned who also reckon chisel-marks are cup&rings. You'd truly be in with a chance there SL.
