I couldn't credibly bluff anybody of that. I've posted some very high resolution photographs of some of the barrows, in a gallery, for photo-editors, and I'm attempting to capture two of the bigger mounds on some trippy out-of-date 8mm film stock (qv the recent Bob Dylan promo-vid). And I'll probably send a complaining postcard to one of the Co-Chancellors (if I can find her agent's address). And there's a prime - but uninvestigated - site for Rock Art to ramble for the first time.
