Guys,
For the last 8 years I have walked the course during the Porter Cup, wow, what a great event at any level, walked two years ago with Tripp Davis, watched Casy Wittenburg win it that year, I'm sure many of you have heard that name recently, rookie on tour and playing fairly well in some bigger events, anyway, the course has unfortunately been chopped up from other GCA's over the years and the original body of work from Tillinghast is worn alot on the edges to say the least.
Records do show that AT did the course, but it is acknowledged weakly in only a couple of references, I suspect he didn't make too many visits and his drawing are limited at best for NFCC. I have never contacted the Tillinghast Society to see/hear their response...
Overall, the course doesn't play nearly as easy as one might think due to the relative short length. The bunkers are hap-hazard in styling and quite inconsistent across the course. But with 90 bunkers and a par 70 many of the countries top amateurs often have their work cut out for them.
Certainly, the par threes are Tilly all the way and if you squint your eyes, you can see his old bunkers underneath around the putting surfaces. The 18th hole comes to mind quickly!
Overall, the structure of Tillinghast remains, but it would take a significant effort to bring it all back.
