Well, after reading Pete G's exploits and wanderings, one can't help but feel a little envious that all the attention is Way out West, when the possible origins of what's out West is over here in the East!
I spoke to the head honcho again this afternoon, he hinted that I may have been looking at the original Neolithic floor beneath the stone, and that they'd brought out around 45 worked flints from the mess left by the rabbits
As I said, I'm off down there again tomorrow, with a bagful of burnt flint and offers of tea for anyone who wants it. And if the site is left over the weekend, I might sleep in the grass alongside just to keep watch. And if I can keep out of their way and not piss anyone off I'll get some more photos. I think they may have enlarged the area since yesterday, so maybe more stones under the road!
Also, Thanet Archaeology's website is hard to navigate, but a wealth of info on Hengiform constructions [yes, possible Henges in Kent!] Causewayed Enclosures and just about everything else you'd hope to find.
