Put me in the cheering sections for the evangelists. I've tried being one--putting my money where my mouth is--and couldn't afford the result. I skimmed through this thread not very carefully and am quite certain I have nothing of substance to add. I do have a sand based golf course with an extremely low maintenance budget that plays beautifully when firm and fast. Convincing golfers, our customers, that this is "proper golf" is, from my point of view, impossible. We'd be broke and closed long before we won the argument or even brought a bit of enlightenment. Yes, we could do it, but there is not a soul on my staff that thinks it is a good business strategy.
This summer we had a very unusual weather event: we got nearly 4 inches of rain in 36 hours, in an area that averages 10 inches a year. So much rain on the surrounding land above our canyon location that everything flooded and caused a landslide when it reached us. It deposited so much material on the course (one hole) all we could do was remove the rock, raise the irrigation heads to the new surface, and re-seed the damage. Fortunately it was mostly sand, hundreds of thousands of tons of it. We turned off the irrigation for two weeks in August--unheard of! The grass went crazy growing like mad. We mowed around the clock trying to keep the course playable. I was horrified about how lush and thick the rough became. You get the point, we did what we could to manage the best we could.
Despite all of these problems, we got the most compliments ever about the conditioning of the golf course. It was a grass factory, not a decent playing surface, and our unsophisticated golfers loved it. I'm sorry to say that I don't have the guts, energy, or the pocket book to fight the chlorophyll junkies.
My resigned approach to a maintenance meld is to keep it watered and green during the growing season and enjoy the golf when we blow out the pipes and turn off the pumps for the rest of the year. We're blowing out now. With some luck and weather, we should have some fine golf for the next five or six months.
