What does it say that three of the five founding golf clubs of the USGA (Newport, Brookline, Shinnecock) have undergone alterations for majors? Certainly, those courses, with their high profile stature and membership, are not making decisions on a whim. The superintendent at Merion didn't cut the rough for an entire year leading up to the Amateur. Needless to say, that experiment did not last. Who is to say that the Newport "experiment" will last either. Honestly, it has only been a few months and reclaiming the fairways may take time. Remember, not all memberships want to see construction year-in and year-out.
I am a member of Newport's sister club in RI, I played at NCC in high school tournaments, and my friend just left the assistant superintendent job there. A course like Newport will always be special.
