than Baltusrol Upper ?
I recall, many years ago, playing in a tournament, paired with a fellow from Houston, who three putted four of them and four putted two of them.
I played the course recently with two very good golfers and one fellow who's an excellent putter.
All of us had great difficulty in negotiating those greens, managing only six birdies amongst us.
I was 0 for 15 on birdie putts.
The rainbow like putts, where pace and line have to be perfect, are demanding to say the least.
Putts above the hole are treacherous.
Is there any other course, where the introduction, the first six holes, has greater putting demands ?
