In this installment of our Golf Architecture 101 series, Garrett introduces his Fried Egg Golf colleague PJ Clark to C.B. Macdonald's "ideal holes." They discuss how Macdonald came up with the notion of "templates" based on famous British golf holes, and they dig into the history and characteristics of the Redan, Alps, and Road designs. Garrett and PJ wrap up by talking about whether the ideal holes have outlived their usefulness.
