I hunt PA, NY, CT, and ME a lot. Seems to me the rut really kicks in about Halloween. Nov. 20 is getting late, but there is a second rut, usually about 30 days after the first for does that did not get bred one the first one. Peak of rut or not, bucks are still active in this time period. I used to hunt the southern tier area (Catskills) quite a lot. Dr. Joyce Brothers used to own a home with quite a bit of land. I was friends with the guy who was her places caretaker. We got some nice bucks there. This was back in the 1980's. This year I am going to hunt the early muzzleloader season up in the Northern zone. Sort of like Maine - not many deer, but not many hunters, and when you see a buck, usually its a nice one. The Oct. 16 opening date is just a little early for the rut, but they are already starting to move some. Great camping weather. Good luck, lots of deer in the Southern zone - Catskills.
