When I look back at my trip to Wales in 2011, I recall one particular place that I have somehow never written about - The National Slate Museum of Wales. I remember a long coach drive through rolling grass-covered hills that filled us with a sense of anticipation for the place we would be visiting. And the place did not disappoint. In fact, I get flashbacks of this place almost every time I think of Wales and that is why this museum deserves a Time-Turner post of its own.
