NO WAY anyone familiar with the geography & geology of the Pine Barrens area of NJ could label the ground beneath PVGC "average."
First of all, the areas of PVGC (and Pine Hill) are about the ONLY pieces of undulating ground anywhere within a 20-30mile radius. It is simply just flat nearly everywhere else within that radius. The rises & falls of holes 2-5, 8,13-18 and the vertical of the waste area on #6 leave no doubt that while Crump, Colt, et.al. were indeed geniuses, the ground was way above average. The firm and sandy nature of the soil certainly isn't average either.
My earlier choice of Kingston Heath reflects on the genius of routing (Mac) and building on FLAT sandy turf, yet if you travel 1.5 miles away, rolling and very moving ground is found beneath one of the world's greatest layouts: Royal Melbourne. This presents a very good analogy of Hidden Creek to PVGC...not much different (just farther apart, yet within the same geography).
Don & Dan....
If either of you had the opportunity to play/see the par 3 course there, it would be even more evident that this was no "average" ground.
