I've played Hunter Ranch 4 times.
My thoughts are that the first 6 holes are quite good, though I'm undecided about the tree in the 6th fairway. The better land is on the front nine...the back nine starts to try a bit too hard. The 10th, though I don't mind it, is a gimmicky start to the back nine, and several of the holes on the back pinch the landing area unnecessarily - the 11th is silly, and the boomerang par 5 around the lake (15, I think...) is ridiculous.
18 is a letdown, but I'm not sure if you can really call it a letdown after a back nine which doesn't equal the front.
It's in a pretty location, and its a very low-key place. The greens are for the most part, large and not overly imaginitive - more gentle sloping than anything else lots of "big and round" going on.
If you're familiar with area courses, I say take the front at Hunter Ranch and the front at La Purisima and you've got yourself a heck of a golf course.
HR also has 3 or 4 little practice holes - 70 yards long or so that are a great little tune-up or cool down.
