Pat-
I agree, the land around the polo field is much much more interesting. Macdonald's ego probably just didn't want to have to give in to polo. If he looked at the property objectively (without being told he had to give the central section up for polo) he probably would have chosen many of those same land features to utilize (#3, #11, #12, etc..), though maybe not the exact same routing.
As we discussed yesterday, and I know we disagree on this, but it is my favorite MacRaynor course.
David-
You are probably correct, most of the land around the course has a fair amount of elevation change, but it would be hard to imagine the massive earth moving process that it would have taken to get the polo field that flat. I always assumed it was graded to some extent but was for the most part a nature valley to begin with and fairly flat.
PS. Does anyone know when the faux chocolate drop bumps and mounds were put in around some of the greens? (#7 comes to mind)? I assume that was a Dye addition some time back?
