I made it out to Wren Dale today and have to say that I'd agree with Jonathan that it is very unlike any Hurdzan/Fry course I've played.
The site itself has some pretty good attributes, but is also intersected by deep ravines that require play as wetlands. From a shaping perspective, it seems that dirt was only moved in some areas, and visually, the course is very natural, unforced, and appealing. The bunkering is scant, and the scultping of those bunkers is visually toned-down, with just very basic lines utilized.
The fairways and playing areas are quite wide and forgiving, and the greens themselves are also fairly inviting targets. Many holes permit run-up approaches, but it's too late in the season to determine if the ground will play F&F enough to allow them to be utilized fullly.
With a yardage of just over 7000 from the tips, it seems that the slope rating of 137 is a bit high. Most holes offer plenty of latitude and forgiveness and water only comes into play on the 2nd' hole in the form of a irrigation pond to the right of the green. Similiarly. woods and OB are scarce.
There is no question that this will be a windy site, but today was a rare still one so I probably didn't get the full gist of how some of the holes might play in a stiff breeze. Still, mixing the back tees with the blues (at 6600+), I didn't get the sense that the course will be particularly stringent in defending against the better player. Two of the par fives are easily reachable, and most of the longer par fours play downhill.
The routing seems determined to utilize the ravines as frequently as possible, which leads to a number of forced carries. The highlight is probably the 5th, which rewards a drive that carries the longest route over the ravine to the right side, and then requires another carry on the approach.
Visually, the course is a nice break from Hurdzan/Fry's often "busy" style, but I found myself wishing that the greens were smaller, more tilted or contoured, or made for more exacting tests. While Wren Dale is a very nice addition to central PA golf, it's missing something on the "excite the senses" scale that the best courses provide. One leaves wondering if the focus on routing the course to maximize the use of the ravines didn't leave too many of the other holes to be much too routine and parallel.
