Jim,
I haven't played it yet, but it is probably the company that it keeps. I have been fortunate enough to play some of the greats on Long Island: Shinny, NGLA, Maidstone, Friar's Head, Garden City, Piping Rock, Bethpage, etc... There are still others I want to play, including Hudson Natl.
How would you rank it compared to the others? I have always heard great things about the course and my next trip it will be on the my list along with Deepdale.
There is a member on this site that hosted a GCA day, I signed up for the trip, but work got in the way.
