Pat,
I have been green typed!
I have also given this a lot of thought over the last four years, having been (for some God only knows reason) posting on these threads. I have at times flip flopped like a politician on these threads, as new info comes to light and is considered. I have NOT been truly argumentative with anyone, since I don't really care if it comes out that it was routed in 1910 or 1911. As such, I find your green type answers to my postulations the more far fetched of our two positions. Just MHO. It appears that you are trying to force their thought process into more modern thought processes.
The secrecy argument is NOT a weak one. It's mentioned in the MCC minutes (according to TePaul) and there were many people living out there at the time on their own farms who would notice people walking in the cornrows. No need for high tech cameras since the MCC boys wouldn't have had Desert Storm type night vision goggles that allowed them to route the course by walking the land at night under the cover of darkness. Think about what YOU wrote.
As to the configuration and size question, yes I agree. But, they had some idea of what it might look like from Barker, and could have figured with more land, it could only look better, no? And, a letter (or if you prefer, even if not proven, possibly a prelim routing by CBM) to guide their purchase. Either way, if he said it would work that might very well have been enough to convince the amateur sportsmen from MCC that it would work.
And, coming from a sub 100 acre parcel, its not hard to imagine that they thought that the parcel was luxiouriously uncrowded. They did look at a couple of parcels, and probably fournd this one most desireable for its location along the RR, the cost saving feature of an existing structure for clubhouse, the ability to work with Lloyd to configure the property to their needs, the fact that members wanted a place where their homes could be next to the club, and its gently rolling topo and natural features, which were generally praised by CBM as great for golf.
There are a LOT of reasons that make a parcel desireable. It has been written in a few books that many features supercede actual natural golf features in selecting a parcel. By 1910 standards (not 2010) the parcel had it all in the eyes of the MCC members. History records that, because they selected and developed the parcel!
