Thank you Hugh, Ian and John
Yes, most pleasant. Where in Wales may I ask?
(My grandfather was from Pembroke.)
So this is a valley in the Black Mountains between Mynydd Troed and Mynydd Llangorse
There are many prehistoric sites here, burial mounds etc
The scenery and lighting were stunning on the day I visited, with many sets of thick clouds moving quickly to reveal bright sunshine & blue skies, then repeat.
It's just across the border from Herefordshire where I live
The words "Area of Outstanding Natural Beauty" appear several times around here in Google maps and they're fairly accurate
