Some good points here. I was a member for 15 years, unfortunately about the last 10 years they started alternating play on the 6th hole with another funky green. So I didn't get to play the hole as often as others on the course. Ownership was more concerned about the condition of the green for the pros then how they treated the members. There, that makes me feel better.
Kirk is right, the new tee in back is bad, all about trying to offset how far today's players hit it. John Daly started hitting 9 irons from the original back tee and it headed downhill after that.
Interesting comment about not being able to go at the middle of the green, truly makes the hole unique. Members don't chip on the green, the pros do. I have seen Steve Pate and John Daly chip, that was fun.
Yes, you can putt from almost every spot to almost every other spot. There was a great front middle hole placement at one time, but it has been mostly eliminated by a new contour there.
Ron Whitten wrote in the Riviera history book, which by the way is well authored, that even without the bunker the green and the hole would be great. I think that is mostly true.
I have seen Proctor and Axland's hole at Bayshore, haven't played it, but it looks good. I know Dan spent a lot of time working on the front bunker at 6, and I am sure he soaked in all the nuances of the green. Maybe I will send Benham some pictures if I can find them, and he will dutifully post them.
