Jeff,
Yes, great courses evolve, but not always iinto something better. I guess most (certainly not all) of us can live with a tee moved back a few yards, or a bunker moved to a more strategic position, but there are many examples of classic courses having being changed beyond belief, and advances in technology are not always the reasons. Paul Turner recently showed how a H.S. Colt course has been vandalised by the introduction of a pond. Sean highlighted another course where a pond was inserted short of a green, for reasons only known to the committee.
You're now familiar with the par three 2nd hole at Gweedore. When I was just a 9-10 year old, someone (I know his name) came up with the bright idea of building a 2 foot high sod wall at the entrace of the green, so that players could not putt from off the green. I was too young at the time to do anything, but thankfully sanity prevailed and the sod bank was removed shortly afterwards. I know at the time, that many people objected, including my father, but it was futile arguing with people that didn't have any idea what they were doing.
Patrick,
I gather you are a pretty good golfer; did that help your credibility when you were persuading members of a committee that such and such a change was not in the best interests of the course? Did it help to give refer to the principles of architecture, or did they just look at you as if you had three heads?
We have many knowledgable people on this DG, but every now and a gain we see a topic with the title "My greens committee is ruining my course". I guess it will continue, but it appears there are signs for optimism.
