I appreciate the knowledgeable, wistful and even bitter dissents, but TOC is not the Mona Lisa. It's not a museum. I'll leave it to the real purists, but, "sacred ground" is the sort of reference that leads to suicide bombings these days. The R&A wants to keep St. Andrews in the rota and these changes may seem like putting a mustache on the Mona Lisa, but at least the Home of Golf is still marginally relevant enough to host the best playing for the best championship in golf.
I was chatting with Buddy Marucci the other day, talking about the various tweaks to Merion for the U.S. Open. They made the course relevant for our biggest championship. Almost all of those mustaches have been removed.
Maybe a new regime will one day restore TOC to the time before Low and Fowler made their changes. By that time the Open Championship will probably be played annually in a Trump links playing at 8000 yards., but all of us chops can play TOC and wonder (wish) if it could still host an Open.
