Oh, what a line of click-bait twaddle.
Look, that list does not strike me as particularly "exclusive to play" because some random Armenian nobody from Nutville, USA has teed it up at most of them - and the ones I haven't is lack of time, not access.
How about Burlingame Country Club? I live around the corner (grew up there as a Caddy) and it was once voted onto a GD list of "Top 10 Snobbiest Clubs."
BTW, Winged Foot is really not much more "exclusive" than Olympic used to be.
Kind of surprised SFGC did not make the cut - the social tension there is 5 octaves above Mariah Carey.
I'd definitely add Pedernales GC to the list - I'd much rather play barefoot with Trigger's owner than endure 18 holes at Shinnecock, listening to Rutherford C. Hamilton III pontificate about his investment banking fortune.
In fact, I'd even let Willie hit my tweaked out driver if he'd let me strum a song on his axe. ;-)
