Tom- I can't discuss the history or justification but I can inform you and everyone that this week the pga club championship is being held at Twin Warriors, here in the land of en-TRAP-ment. The revetted bunkers there, are maturing beautifully with the rugged natural grasses being used as a visual transition to the native areas on perifrial or the outside edges of the fairway bunkers. The greenside bunkers all have the revetted look and some even emulate Ross, in that they abute the green very closely. Any shot short is sure to find these deep beauties.
I played the course twice yesterday and the rough was higher than Olympia fields and the greens were firm and rolling near 13.
The CPC will air on the Golf channel this coming weekend.
I encourage everyone, especially GW raters, to get there someday.
