I don't fault the USGA. They have listened and tried to respond to the likes of some of we golf purists who harken our whimsy back to the old sod and have asked for more traditional golf conditions and more linksey courses. They put Chambers and Erin into the rota along with many grow-in years of support for the fescue that we all fancied.
Yet, I think it is fair to say that fescue has been a repeated failure at Chambers and just about everywhere else it is tried in North America, particularly the PNW and west coast. It doesn't seem to be anything more than a climate and soil type issue compared to where fescue seems to thrive in GB&I. I surely am no qualified to say that definitively. But, it sure seems like a rapid poa invasion is an inevitablility that can't be managed.
While the newer rebuilt greens at Chambers are much better than the older ones, it seems to me that even if they converted them to some cultivar of Bent, poa would come into the sward faster than most bent facilities yield to the poa in other parts of the country. So, even with 5-10 year old new bent greens, poa would likley be significant percentage of the sward, and they would be putting on broccoli top like greens of poa anyway, at this most prolific seed head growth period of the year.
Maybe what we really need is a very intensive research and development in the turf seed botany field to find a new cultivar or new hybrid species of greens turf that will hold up to poa invasion and climate.
At the end of the day, it is still a decent leader board. So, may the best golfer win regardless of the conditions that are essentially the same for every other golfer in the field. I'd still love to play Chambers from 6200 or so yards....
