Sean's point about the ratio of subscription to daily green fees is an interesting one. As a country member (importantly), I reckon the ratio at The Old Course and Harlech and Porthcawl is about 2.5 to 1, but of course joining is not necessarily as simple as filling in a form (!), and even once elected there may well be a significant entry fee (although not at Harlech).
What does sadden me is that the days when a group of keen and competent golfers could plan a trip to the coast, involving perhaps one 'treat' day at a championship venue and two days at good supporting ones, and reckon on paying no more than £300 for the privilege, have disappeared, with (it would seem) the exception of Cumbria and North Wales. And it's always worth emphasising how unusual parts of Scotland and Ireland like Dornoch and Ballybunion remain in their proportion of North American visitors to British ones: the very large majority of 'visitor' rounds in both England and Wales will be played by golfers from the British Isles.
