For me any golf is a day well spent, no matter where.
So I'm gonna go along the lines Bill Gayne has started.
It would have to be NGLA.
Why you say? Golf hell? Has the man gone insane?
Well remember this is a lifetime. As great as that course is, eventually one would want to branch out. And having Shinnecock and Sebonack right there IN SIGHT, so close but yet so far... well that would be the greatest golf hell.
Kinda reminds me of my daily commute a few years ago, parking next to SFGC every day.
