Michael,
Not true by a long shot. I used to think the same thing as you, but after getting to know a lot of guys out in the Desert, they've taught me different as there is in fact a rather large aquifer that supplies the entire valley, as well as the All-American Canal which handles most of the courses in La Quinta. That water comes from Northern California via Sierra Nevada run-off.
Martin,
Count me in with the Doak faction in thinking that Stone Eagle has turned out to be an exceptional golf site. I think Tom has produced an extraordinarily fun golf course to play. It's just when it was 111 degrees F, and your on your second round of the day in that kind of heat, something's got to give.
As far as the rest of the desert, and to get back to the point of your question, the desert provides some dramatic landscape with little or no problem in confusing it with seaside links, other then there is no large body of water which cool breezes can blow from.
This particular site is about 10-15 minutes away from the Stone Eagle front gates. Unfortunately, or in this case FORTUNATELY it is protected and will never be anything but sand dunes. (ha ha ha, I'll believe it when I see it in twenty years!)
So you see Martin, this beautiful arid and dry desert is perfectly suited for ball and stick. Some of them reminscent of the same type of ocean runOne can also moan the loss of many other parcels just like this, where sand waste pushed and formed to create tract housing pads. It's was a contagious out-break that was controlled and exlored
