On the advice of Brownhills Bob I took the tribe to see New Hall Mill this morning. What a fantastic piece of local industrial heritage! We saw the mill at work from grain to grind to flour, and eldest son won himself a pencil for spotting rats and solving the final anagram.
I heartily recommend you visit the mill on one of their regular but infrequent open days. Had the sun been out a picnic would most definitely have been in order.
Cheers Bob! Good call.
