For the upstate NY contingent here's this.
Glens Falls is in Ian Andrew's world Top 100. Tom Doak has posted it is a course in our area on his "to see" list. It's a Donald Ross course. I have not, yet, played it.
Leatherstocking is a fun course with some interesting holes. Personally, I rate St. George's above it on the Emmet canon. My understanding, maybe flawed, is that Les Rayner the pro there added the 18th tee out in the lake at Leatherstocking, which is cool, but the 16th, 17th, and 18th are out of character with the rest of the course. That said, Leatherstocking is Emmet quirk through and through.
Here in the states, Emmet was a prolific Golden Age architect, but certainly he is overshadowed by Ross, MacKenzie, Tillie, Flynn, & MacRaynor. When I mentioned my theory that Emmet was a 2nd tier architect to David M., he objected, saying Emmet was definitely a top tier GA architect. Based on the rankings, you wouldn't think that, but then again, the competition is tough, and judging by St. George's NY and Leatherstocking, Emmet created fun courses with quirk not muscular, championship tests. That seems like the kind of course that fits the bill, here, so maybe this is the list he gets his due.
CC of Troy, a Travis course, I haven't played since well before my GCA baptism. However, it was one of my GCA drivers, as though I had no vocabulary to describe the course I knew at the time it was a cool course. It had that "it" of greens and hazards, contours and routing that an observant if not knowledgeable neophyte keys in on.
Are these four courses in the Top 50-100 sub-6500? I don't know, but, I do know that these are well regarded courses by top architects and certainly worthy of consideration.
