Dublin was enjoying heat wave. Wednesday was an afternoon off. I caught the Dart train to Greystones, the end of the line. Greystones is a delightful tiny town in County Wicklow, Ireland. It lies on Ireland's east coast, 17 miles south of Dublin. TheWicklow Mountains rise up to protect this area from the West. The town was named after the grey stones which ran between the two beaches on the sea-front.
