Oi, mate. I've an Auntie who was there in '55. I'd love to get some of your recollections for her, as would some others on here. Would you mind or shall we take it to PM?
Ask her if she remembers the wooden cafe (now rebuilt) near to the Crosville bus stop for the Ruthin and Mold services. We used to stay in a wooden shack up in the woods outside Pantymwyn (another nearby village was Cilcain) and I'd walk through the woods (apparently inhabited by adders) and down to the cafe which had a juke box.
In the spring of 1964 (so a bit after your auntie) my abiding memory of the jukie was Roy Orbison's "It's over". Not quite the Beatles or the Stones the 11 year old me went for but there was something powerful about it.
There was another walk which took you to the Devil's Gorge an old mine working. Even now the area still has a thriving quarry industry.
I've taken my children and grandchildren to ramble around the rocks and to get their feet wet in the River Alun, which never seems to be more than one foot deep.
