Not trying to stray too far from the stated topic of this thread I will tie in C'willa.
On the Harmony exclusivity issue, I will say from personal experience that Kent and everyone else I met at Harmony were the epitome of gracious without a hint of pretention, something sometimes associated with exclusivity.
Remember, Harmony will provide those in the Lake Oconee area with a truly private club option, something entirely lacking there now. In comparison, take C'willa which I liked so much that I bought a little cottage there and got my membership on the spot and even played in the member/guest the next weekend, which was awesome, and everyone we met were good guys not unlike our GCA experience there the weekend prior, but no matter how you slice it C'willa is a resort course with a private golf club within it getting the best tee times, etc. (that may be the longest run on sentence I've posted).
Every great and very good golf course serves a purpose IMO and C'willa gives anyone the opportunity to tee it up on a very special tract of classic style GCA. This I admire greatly. In fact, I heard mention that Friar's Head was planned to be a very similar resort type facility (which would have been a gift from the gods) but town boards got in the way.
I think Harmony will serve a different purpose and enable some an opportunity not readily available these days (completely unavailbe on Long Island, for instance). There are a few projects and/or new private clubs that are being built as a golf club first, for a membership but pure golf without pretense, and, in addition, projects or courses that remain a viable financial option for those with net worths below $10M.
Harmony will certainly be one of those admirable few.
