Mitch,
I spoke to your friend, Marty, and got a little bit of information on Womens' National, now Glen Head. George Holland, the historian at Creek Club found billing records (the club was part of Creek Club for a time) that shows significant payments to Flynn in 1926 and 1927 (>$15,000). I have yet to determine what Flynn did there, but the bunkering looks nothing like another nearby Emmet, St. George's. It is possible that Flynn remodeled the bunkers as a 1940 aerial shows marked differences as compared to the Emmet plan.
Now, back to cheesesteaks. I hope you didn't go to the Jim's on South Street. The original one on 62nd Street is the best. Mama's on Belmont Ave is a different style, but quite good. A belly bomber at 2 lbs or so.
