Looking at those photos, I couldn't even tell work was being done, but the caption says, 14th and 16th green or whatever. I looked and was like........OK I guess this is really minimalist.
Haven't been to Sand Hills, but went to Dismal and Ballyneal last year. It is a wonderful discovery of golf playing in that country. I maybe in the minority, but having golf carts will allow those "well to do" members to still use the course as they age and having it as an experience to do with their children and grandchildren.
