Point taken about a 'Slates to the Sea' conference Dave. As you say, possibly something for Plas TyB.
My thinking would be to look at all the slate regions of Wales and how they 1. extracted and processed the slate 2. got their slates to the sea and away to market 3. how the expansion of the extractive industries led to whole new towns and industries (eg. foundries, shipbuilding, banking / commerce, food production etc, etc) around them.
So we have Penrhyn, Dinorwig, Moel Tryfan, Nantlle, Croesor, Ffestiniog, Talyllyn and Corris groups of quarries / mines.
There was of course some metal ores shipped from the same ports but compared to the slate tonnages, comparatively small...
Too wide a remit? Just my thoughts.
From looking around at the conference, we need an injection of younger blood (unless they were all on the the mine visits...) How do we attract the younger generation?
