Having only played the course once, I can certainly say that this place is an "eyeful". I can not find another course with such diverse conditions. The only two other courses that compare with the elevation chagnes are Triology and Coyote Hills. I was lucky to have been with a four-some and did not have to wait for as long a some previous golfers. My round was only 4 hours on a Friday. All groups kept up the pace infront of as well as behind. I agaree that the greens were dreadfully slow and that OB's were a constant threat. However, if you want to play a safe course, you would not necessarily pick Oak Quarry. Being a 20+ handicapper, I would certainly suggest that everyone play this course but be prepared to bring plenty of golf balls, I had to scrounge on the course to find an extra ball to finish the round. This is not for the faint of heart, especially the siganture hole! Fortunately, as with others, I did not find it terrible crowded and it played fairly quickly. But as it becomes more and more popular, I am sure that the times may extend well beyond 4.5 hours per round. If that happens, take your time; look at the scenery and watch out for coyotes roaming the fairways.
