I know I am (along with my companions that day) to have played:
AM: Century (NY)...a sumptuous, exclusive, and pleasurable US Top 300 Colt-Allison collaboration. An ultra-desirable get even in these considerably rich parts.
and
PM: Sunset Hill (CT) my adolescent first course, an arcane scruffy 2350 yd public first made as a practice course by Gene Sarazen in the 40s. This day, we did the first 9 with three clubs and the second nine with the other 11 we didn't use.
While I can't be certain, I would be somewhat surprised that someone else has played:
WFW & CC of Fairfield (maybe my best total day of playing ever)
and
Fenway & Trump-Briarcliff (maybe my least favorite day of playing golf ever, though it is the foundation of perhaps the single most hilarious bull in a china shop incident I have ever been part of...relax, it was several years before Cheetus I's political ambitions were realized, when he was just a joke for the costly excesses of his burgeoning shit club brand)
