Huh? Pembrokeshire was infinitely friendlier than Angelsey and I had a splendid time at Brawdy in 1975-6. Apart from the local Taffia who ran the Officers' Mess pulling union action now and again...
The OM at Valley was quite pleasant back in the 1970s. Especially when Mary with the long legs used to run the 'Dragon room' - where a couple of bratties and a pint or two would finish off many an enjoyable evening's revelry. But all gone now and there's just the one big soulless place. You are right though, the oiks were kept well away. There was a fair bit of socialising with the local expats (non-Welsh) - often centreing around the 'Sandymount' in the nearby beach village of Rhosneigr. Anglesey was 'dry' then on Sundays, so to to get a drink on Sunday you had to be a member of a club - as all the Officers Mess were.....
Only one bridge across the Menai and no dual carriageways meant that excursions back to England were rare, so we had to make the most of the place despite the rudeness of the locals. They once made the mistake of mouthing off about a group of u/t Gnat students in a local shop in Llangefni - big mistake for them as one of the group was fluent in Welsh and gave them the full benefit of his linguistic ability!
The only thing which spoiled Coningsby when I was there was that Ba$tard Bill was Stn Cdr - otherwise a very reasonable spot. But not as nice as rural Wattisham down in sunny Suffolk- and at neither of which was life anything like as truly excellent as it was at Scampton was in the late V-force era of 1977-79!
