Ed Baker,
I think TV, winter vacations and lunacy amongst the membership are the real culprits.
Everyone seems to forget that their course is a course for the members, NOT the PGA TOUR PROS, but, somehow, they think, that in order for their course to achieve credibility or notoriety in local/regional/national golfing circles, that it has to be diabolically difficult, and that usually translates to more distance, faster greens and deeper, denser rough.
There's an element within every club that feels that their golf course must mimic what's seen on TV every week, difficult golf courses that challenge the best players in the world.
I pointed out the exact same thing that you did when some wanted to lengthen a course that I'm very familiar with, AND, they wanted to make it more difficult, they wanted to increase the slope.
I pointed out that NOONE has broken par in qualifying for the club championship in over a decade, that a score of 8 to 10 over usually qualifies for the club championship, so, who are we trying to make the golf course harder for ?
When golfers vacation in Florida or the West, they meet other golfers from other clubs/areas. Suddenly, bragging rights about how difficult their home course is, is the topic for discussion. Armed with this newly acquired nonsense, they rush home to fuel the "difficulty" race, insisting on added length, faster greens and deeper, denser rough.
The cause takes on a life of its own, and led by golfers who can't break 90 or certainly 80, the club embarks upon a project to "beef up" the golf course.
It's insane.
Golf should be a challenging journey, requiring thought, that produces fun, not a survival of the fittest contest.
Sadly, most clubs have lost their way.
