Holidays. Some people laze on sun-drenched beaches. Linda Acaster ventures down Neolithic
flint mines.
Collect your hard hat and join her and hubby as they fight their way through Thetford Forest, Norfolk, to descend
30 feet into Grime's Graves - or at least "Pit 1" to view the narrow galleries where black flint was prised free with the aid of antler picks. And a lot of sweat.
