John Low,
Am I correct in stating that you've never actually seen the Road Hole Bunker or the 17th green, in person.
There is no room to insert a bunker to the right, or back of the green.
A roadway/path are immediately adjacent to the wall, and extend, almost to the edge of the footpad of the green.
That isthmus of land between the roadway/path and the green would be the only site that a very narrow bunker, below grade, could be installed.
I don't recall anyone ever suggesting that a strip bunker be installed in that location.
With respect to Mike Cirba, he an I know each other and our views fairly well, and I respect his opinions, even if some may not align with mine.
Rich Goodale,
The road and pathway would have to be removed and relocated and perhaps the powers that be have decided the effort and disruption don't justify the replacement of a pot bunker, especially when you describe one of its functions.
