Hi Jim,
I played Astbury last year, only a few weeks after it officially opened.
To say it was in excellent condition would be an understatement as it was possibly as well presented a course as I had seen. The greens especially were very true and exceptionally fast. It is my understanding that Troon are managing both the course and club.
I haven't been back since then, however have heard rumblings that many of the greens have needed to be reseeded due to the cultivar that was used initially having not coped well and in some cases failed altogether.
As for the course, it is an okay layout albeit fairly short (6500 off the back most markers) with the last hole - a par 3 over water - being the standout hole. There is possibility of there being another 9 / 18 holes being built on adjacent land which is part of the property.
KK Downing is very hands on and when I visited was actively chatting to visiting golfers in his own inimitable style; nervous tic and all.
I'm not 100% sure but I don't think the club is affiliated to the EGU and and such the members don't have handicaps - I know of a small number of local golfers who have a 'membership' there but use my home course to maintain their handicap.
As for the realisation of a dream - I believe KK Downing's story is one which many of us would love to replicate.
Neil.
