Folks,
Interesting replies, especially Tom's reference to 14 and not really getting enough out of the property. I can't speak to that, but it does require less thought from the schlepper than most others -- if the wind is helping, try to hit it over the hill and down, and, if not, play out to the right. I think the green is a comparatively simple (compared to the other greens on the course) Biarritz variation, though others might think that this less wild green lends variety to the course.
From my relatively brief experience, the gunsch is actually playable early in the season after it gets toasted, though I'm not sure about late. The course seems plenty wide, but it draws balls like crazy anywhere.
Couple things make this course special to me -- it is so different from the parkland golf I'm used to, and is also very difficult, but the difficulty results in fun shots rather than just stuff that can't be done. Not much in the way of forced carries and extreme difficulty near and on greens will do that. Also, the members are terrific, as people have noted.
The other thing that makes the course special to me is the guy in Ian's picture. A great friend, who insisted that I get to Prairie Dunes when he found out I was moving. Basically joined me to the club.
