Since non-golf-writer raters are not compensated (beyond the golf) to the best of my knowledge, theirs is a volunteer industry.
Some states have a top 15 list and that's it...not enough great courses to be listed. When it comes to New York, you have 15 great courses on one island! 15 more in one county! and another 15 across the state! Three separate districts, so how do you bring them all together and determine merits.
I wonder if there is a single Buffalo gal or guy, a single Rochester gal or guy, a single Syracuse or Albany gal or guy, on any of the rating boards. If there aren't, and the rater list is populated by NYC Metro names, it's no wonder that upstate (pretty much everything north and west of the Catskills and Westchester) gets short shrift.
