NO.
I live in the Hudson Valley (Orange County) New york. First off, New York is a huge state, and there's a lot more to it than just NYC. The Hudson Valley is beautiful, but as stated before, the taxes would drive Disney away. Plus there really Isn't anywhere in the Hudson Valley for Disney to build a major park. The majority of people live in huge developments or gated communities. No matter how much I love Disney, I would never want all that traffic and confusion around me. Plus the amounts of snow during the winter would mean the park would only be open seasonally. Unlike Orlando and Anaheim, the Hudson Valley experiences all of the seasons full throttle. Even if Disney could over look these problems, I guarantee you locals would beat the project down; the park would never get built.
I think Disney could find more practical places, across the country, to build another park.
