Jeff, Don't we have to put ourselves in the context of the times? 1987-88 was a weird time for golf course construction. One could even argue that it's product led to the masterful more natural courses you mentioned.
Im not sure it's a romantic or emotional view that I have. (although I'll admit to being a teensy bit angry over the near loss of the original. Since it's still 99% playable I'm not angry) I just know that the course grew in it's naturalness, in a way the current does not. The impact of those later holes (Valley nine) was all set up by the earlier ones. And truthfully, the mounds between #1 and #2 and the 4th and 5th holes, due to the artificial pond, are the only objectionable aspects of the courses design, from a natural viewpoint. (angular architecture aside) After the 5th hole there is very little one could call a bad hole. Even by today's standards.
My comments are meant to contrast the original route with the current River courses route. Rather than have a journey that leads somewhere, as the old original did, the current routing of the River course goes nowhere, in a journey/adventure sense. Mostly because we come back to that stupid Pond hole the current 14th and the course doesn't utilize the Valley nine.
I'll say it again, each of those holes 5-13 of the current River course are all fine and fun golf holes, but, they do little to accentuate the whole course and make for a weaker (not as great) golf course. It's falling position in the rankings over the years suggests that it has lost a lot of luster.
One of the keys that tells me Pete was thinking about all this naturalness stuff, as instrumental, was his NOT putting a rear exit ramp on the 14th hole. Forcing the golfer to retrace back towards the fairway, getting another glimpse of the most serene untouched area that sits between 14 fairway and 15 green. If someone sees that, and feels nothing, they are either unaware about anything but their own selves and game, or, are emotionally inept to feel the serenity on display.
I remember the scorecard had the quote from Pete " The most natural setting for golf I have ever seen". I didn't even know what that truly meant until years later when I first read the home page to this website. So, once again, I don't think I'm basing this opinion on emotion, just applying what I learned from being exposed to the early days of GCA.com when core and artistic principles were paramount considerations in both text and subtext of most discussions.
