I first encountered Irish golf back in the 1960s with my father. In those days you could turn up pretty well anywhere and any time and walk out onto the golf course as a green-fee paying visitor. It was not expensive, even at Lahinch or Rosses Point (we didn't play in or around Dublin). In general the Republic was cheap (petrol, food, hotels etc) whereas Northern Ireland seemed to be considerably more expensive than mainland Britain in terms of petrol and food, at least.
The last time I was in the Republic (not to play golf) I was amazed at the transformation: the opulence of the stud farms and big houses, the number of big Mercedes on the road, the formerly deserted white-washed cottages in Donegal now going for €1 million, and the horrific price of food and hotel accommodation. I remember thinking frequently, 'This cannot last!'
In a funny sort of way I'd be quite happy to see the downfall of some of these ultra-expensive golf resorts (for I shall never afford to play there) as long as the members' clubs survive, the Tramores, Bundorans, Heaths and so on: straightforward, friendly clubs, welcoming visitors and offering very enjoyable but simple courses, comparatively easily built and maintained.
