John Foley:
Wolfert's Roost is in Albany, A Tillinghast which is relatively obscure. Some of his other Upstate courses include Niagra Falls, Bluff Point in Plattsburgh, Oswego and Binghamton CC.
As for Orchard Park, I am not familiar with the layout. Judging from the quality of his other upstate courses, I'm sure it is very good.
Also if you are including Greystone, I will have to add Cobblestone Creek to thelist of good Rochester private courses, even if it is a bit "housey"
A few more golden age courses from the upstate:
Grover Cleveland Park Course (site of the 1912 U.S. Open!)
Leatherstocking (Emmet)
Sagamore (Ross)
Rip Van Winkle (Ross)
Irondequoit (Ross)
Locust Hill (Seymour Dunn)
Cavalry (Wilson)
Corning (Winton)
Tupper Lake (Ross)
Onondaga (Thompson and Wogan)
Glens Falls (Ross)
I have not played all of these course, but if there are any questions on the location, just fire away.
