On a somewhat related note, do the other GCA members find it odd that so few members of clubs like Oakland Hills, Riviera, Merion, etc., etc., etc. have any apparent concern about the USGA's long-running inaction on equipment technology? I have not yet found a single Oakland Hills member who has any concern about it. Yet their #2 tee is backed up to the fence bordering the property. As is the #15 tee. And holes 1 and 10 are land-locked. They have maxed out the property for the upcoming PGA Championship, and if they wanted to try to squeeze out some more yardage (basically just to add overall yardage, not to make strategic changes) they would have to start tearing up some of their Donald Ross greens that have been in place since about 1918.
In summary, the people who would have the most "skin" in the ball rollback debate seem to have almost no concern about it.
