I've been hunting in Delaware County, near Walton since 1975.
We consider anything south of route twenty souther tier.
NYC is down state for me. Westchester, Putman, Delaware typically down state.
Delaware, Ulster, Greene and Sullivan Counties are Catskill region and definitely not considered "downstate".
I have to disagree with some of those counties, we consider everything below Roscoe to be "the city", especially Sullivan County, aka the Jewish Alps.
Good luck to all you guys, where ever you hunt!
