I think the ability/potential for unirrigated edges to transition to the sandy stuff is more effective makes a lot of sense and I hadn't thought of that so thank you Don for this paragraph...
"At P2 it looked like the best lies were down the middle, got a little more sketchy as you got closer to the edge, and then somewhat inconsistent as you got off the turf. The bleed out started from the middle, and it got dryer and firmer as you worked your way to the outer edges of the hole corridor. I thought it was absolute genius to maintain a course like that. I understand not all will agree, but as soon as the goal becomes a consistent look through the green, it's all lost, IMO."
I want to make it clear, I'm not looking for a consistent color across the playing area...that said, I do think a consistent maintenance of the playing surface is a worthwhile goal. In other owrds, I think the links courses all natural maintenance (with low spots green and high spots brown) is preferrable to what we saw at Pinehurst.
My real concern here is the phsycological challenge presentd by the two distinct options in irrigation system design.
With wall to wall irrigation on efficient computer systems as MClutterbuck has advocated here, the challenge is discipline. How can the club committ to not overusing it? The other side I see is, as presented, there's going to be a real committment challenge to those in power at Pinehurst to remember and strive for what they presented last week and this. A year, maybe 2, maybe 5 down the road, someone is going to look at the prepared playing corridors and see some percentaage in poor condition due to lack of irrigation and decide a change needs to be made...what will that change be? Or will the club stay committed to this presentation through complaints from their $450/round guests?
