TEPaul,
The topography is vastly different, the geological history of the land is different. At one time the Hempstead Plain was thought to be the largest of a certain type of desert east of the Mississippi.
I'll have to research photos pre 1936 which do show mini-forests, (for lack of a better word) in pockets on the golf course. Since 1936 tree and shrub infestation altered the look, feel and play of the course, becoming so intrusive that shots from the fairway to the green were blocked by tall trees.
Thankfully, most are gone and the improvement to the course immense.
The photo of Pine Valley, in the big room, next to the exit to the parking lot reminds me of some 1936 photos of GCGC where trees are at a minimum.
I don't know what Crump's intent was, to keep it free of trees and shrubbery, or to let them grow at random. I would favor the look of the photo in the big room.
My recollection is that this tree clearing process started at Shinnecock, in preparation for the OPEN, was adopted by
NGLA, and with those two, has sprouted up everywhere..
Just look at the Picture Steve Sayers posted of LuLu, and ask yourself if you'd prefer it then, or as it is now.
Trees have a place on some courses, but on those where they were mostly absent when built, I see no need to add them, irrespective of what Dr. Katz may say.
Just ask messrs, Steele, McCullough, Poulan, Black and Decker
