Yes, two years is also way too frequent...as I said in my post, I accept GD retaining any brand item as best they can...it's just another reason the list hardly serves a meaningful function...5 years, 7 years, 10 years...it might get back its fullest buzz and novelty...
In 1985, I didn't know 2/3rds of the courses, only a handful with any play or intimacy...the world has changed, now I have as full of coverage as I want for America's Best 500, a click away and I've probably played or visited 25-30 on the current list, maybe as many as 45-50 of everything that's been on the list at one time (and fallen off).
I needed Golf Digest (and this list) if I wanted to know anything about an near-equivalent decades-young course in 1985...Nowadays, I have full coverage of Sand Hills, Bandon and Seboneck, even though I unlikely to ever get to them, just as I never visited Oak Tree or PGA West or Kiawah Ocean.
In the pre-digital era, it was one of my only links to old championship courses too...like Canterbury or The Country Club or Inverness...it was an excellent launch point.
However without recalling specifically, I'll bet a healthy portion of today's Top 20 were in the Top 20 in 1985...PV, ANGC, Cypress, Pebble, WFW, Merion,
cheers
