I humbly submit that the grass has not a damn thing to do with why the course hasn't been GD ranked yet. I think much of it simply has to do with the number of plays from GD raters. I also think it has a bit to do with the lack of tee markers, the lack of a formalized slope, and the location. The "unconventional-ism" that is Ballyneal isn't accepted by all. Like I've said before, it's remarkable for what it's not.
Some say it's the private version of Bandon. Some say it's the "anti-Sand Hills". Either way, it isn't the first prairie links course and it isn't the first course with fescue greens. Is is however remote, private, and unconventional. And I gather that the 104 members prefer it that way. I loved it the way it is, and I hope that it remains that way as well. Who gives a damn if it is ranked.
