Brian,
Go look in any old book that shows Scottish and British Inlandand Highland links and you will see rough and rugged bunkering most everytime.
Could it be perhaps you've been Lethem Granged to death, one too many times in your lifetime?
But I think you bring up an interesting point, and I thank you for that, because the only cons on the course and it's photos are usually the ones that despise rough and rugged bunkering in the name of contrarianism. You know the Usual Suspects!
I've seen but haven't played the Dukes Course, and personally, I thought it was a complete waste of time to even want to go play it. In fact, I think my B&B I stayed at was closer to the Dukes then it was to the Old Course. what I saw was on a par with a rank muni course here in the States. Judging from the images, it looks like Phillipe, Kye Goalby, Dan Proctor and others got the job done. I think the bunkers look like hazards, which I would like to remind you--that in nature, weather and erosion probably fit this bunker style perfectly. But in the Big World theory, that's a good thing.
Also, I might ask, do you think the current bunker scheme fits the Old Course? Personally, I think it sucks, and would rather see the rough and rugged nature of a sand hazard returned to being what it is--a hazard.
Congratulations to Tim Liddy and crew. It looks like on the next trip to Scotland, a revisit to the Dukes will be in store. At least it looks good enough for a visit.
