New York City is such a huge cultural and tourism icon it is very hard to effectively write a great set of New York travel tips. New York City remains one of the world's great cities and most significant business addresses with tens of thousands of corporate headquarters and company offices. The New York Stock Exchange and Wall Street rank among the most important business venues in the world. New York is also a tourist mecca with restaurants and lodging of almost every conceivable type as well as globally known attractions like the Statue of Liberty and the Empire State Building. I have not been to New York City in many years, though I was lost in the Statue of Liberty as a kid. I still remember that lady of liberty with some trepidation.
