No problem, help yourself :-)
The picture isn’t brilliant but the one on my site is a bit clearer as the join lines are edited out. I’ve got some more photos – again not brilliant – I’ll email you directly later.
Your draft is looking good, perhaps you could add something about the impact on the local population, I’m sure they’re not keen on having mining going on on their doorstep (unless the entire village is employed by Tarmac). When I was there just after Christmas I passed a group of families taking their kiddies down to the henges on their new peddle karts/trucks, it seems to me that the sites have probably been used as a giant adventure playground by generations of villagers. A bit of local opposition to the mining on social grounds could go a long way?
