The Mueseum of Radio and Television is one of the coolest muesums I have ever been in. You can watch virtually any episode of any TV show that has been produced, you can also watch TV commercials. Very cool.
Its on 52nd Street, I dont know the streets its between.
Go take a look at the World Trade Center site. While its now just a huge gapping hole in the ground, it will still give you an idea of the sheer scale of what took place there on 9/11/01. It may really open your eyes when you realize that two 110 story towers once stood high above the lonely foundation. I havent been back to New York since June. I hear that the site is now surrounded by venders selling all kinds of crap in regard to the trade center towers and the attacks. If that is the case, it will surely show a disgustingly disrespectful side of our country.
Besides that go take a boat ride out to The Statue of Liberty and then over to Ellis Island. You catch that boat from Battery Park. Be carefull in Battery Park. Alot of slimy venders straight in from Africa will often times flock around you trying to sell fake rolex watches and Oakleys.
Also Go check out NBC at Rockafeller Center, as well as Time Square which is right around the corner. Not far from their is the Empire State building. $10 or so US dollars will take you to the top.
Of course you must check out Wall Street and Central Park. While you walk the streets of Manhattan keep your eyes open for the great little pizza shops! there you will find the best pizza on earth!
