I'd suggest writing to the Secretary of APPAG, who is :- Lord Redesdale, House of Lords, Westminster, London, SW1A 0PW.
Please don't mention my name, nor the suggestion that I made (which was he should be able to identify Tarmac board members and ask them to 'lay off'). He's a fun chap and is genuinely obsessed with archaeology.
Better not to say anything about those three henges being placed like Orion's Belt.
