A course can be great just as soon as it opens.
But does the club have the proper infrastructure in place to stand the test of time? To me, that is the question. The actual golf course is only one of the players on the stage. Ownership, members, staff, maintenance...do they all embrace the same goals? Did they have the correct financial foundation built prior to opening? Did the architect, and his team, build a course that will stand the test of time? Do the owners/members understand, and accept, the architect's vision? I could go on, but I'll stop as I think you all get the point.
"Will it live?" Perhaps when that is answered, your question can be answered, Mark. It is great if the course is good enough and we know that it will survive long-term.
