Located at the mouth of the Hudson River in southeastern New York state, New York is one of the world's great cities. The city has become a hotbed of seasonal and locally sourced cuisine – with restaurants raising vegetables on roof gardens or their own upstate farms, sourcing meats and seafood from sustainable outfits nearby, and embracing artisanal everything. One of the original 13 colonies, New York played a crucial political and strategic role during the American Revolution. It has the largest population of any city in the United States, and it is unrivaled in the diversity of its neighborhoods and their often-colorful residents. Culturally speaking, it's an exciting time to be in New York, with the arrival of new theaters, cultural centers and sporting arenas (Theatre for a New Audience, BRIC, Barclays Center). A major financial and economic center, it is also a cultural mecca that has attracted generations of artists and intellectuals and draws millions of tourists every year. New York City consists of five divisions called boroughs. Manhattan and Staten Island occupy separate islands. The beloved Holiday Train Show presented by the New York Transit Museum is back, kicking off this weekend at Grand Central Terminal. Bird-watching newbies can head to Prospect Park on Saturday to learn about the basics of bird watching.
