Pros:
(to the uninitiated: this is a temp course, set up one day per year)
This is a beautiful piece of land, rolling hills of green, a pond, trees, and flowers. These are the best set up temp holes I have seen -- good baskets, pads and markers for tees, and nice mando signs. There are some very cool holes. For example, hole 3 where you shoot from an elevated tee over the pond or 14 where you come through a gap and then up a steep hill to a defended basket. The course is easy to navigate and flows well.
Cons:
Most of the problems stem from the limitted amount of land. Many holes play too close together. There are also OBs and mandos designed to ameliorate this which feel gimmicky. A number of the holes in the middle of the course just go back and forth across a big field with a few trees. There are also a lot of holes which are just boringly straight, and the turning holes are enforced by mando, not by the trees and landsape. Some holes definitely end up in NAGS territory -- unless you are a consistent 375' thrower, you're probably look at a number of wide open 100' - 150' foot approach shots. Route 422 also runs right along the course and detracts from the ambiance.
Other Thoughts:
It makes sense that this course only has DG one day a year. There's a lot of nice landscaping that would get trampled too much by a permanent course.
