Bill,
Each one of the sod wall bunkers were built by different people.
Hole # 2, The Strath
Hole # 5, The Cross bunker on Hog's back.
Hole # 6, The Dark hole behind # 6 green.
Hole # 6, The Beardies on # 6
Hole # 11, The Road hole bunker.
Several people including Smiley ( Stein ) Mustache Mike, Crago, Macarten, Reisetter, C.J. and Carl
My only instructions to all of them was to have aprox a two to three finger spacing laid back on each layer as they worked there way up to the prescribed level.
The waves in the top line of the Strath were done by Jonathan Reisetter.
That's why each bunker has it's own personal touch. it's the little things, maybe not perfect but for sure different.
