I always could forgive rough conditions on tee boxes, fairways, even collars of the greens, but not the greens themselves. I also played Bethpage back when it was 7.00 to walk and was in horrid condition from tee to green, but the greens were playable, and the holes were beyond memorable, even if they were severely run down at the time.
Best recent example for me was/is Apache Stronghold. It wasnt in the best shape from tee to green, in some places, it was barren of grass in the fairways, but the greens rolled true all day long, and it is still one of, if not the best desert course I have ever played. If they ever got that course in even average condition from tee to green, it would jump right back up in the rankings.
Just my opinion.........
