Just a few more items.
1. The Intrepid Museum on West 42nd Street by the pier. It's the Aircraft carrier, the sub, and I think the destroyer
2. Museum of Natural History, along with the Met probably the two best museums in the city.
3. If you haven't seen Attack of the Clones in a DP theatre, go watch it at Clearview Zigfield (spell?)
A note about Central Park, I really like the ducks. Bring something for the ducks.
And don't just get stuck in Manhattan. If you come to Queens, you should probably visit Flushing (yes, the Flushing Meadows of the Simpsons fame, there's a section of Flushing that can be considered a second Chinatown). I live near Forest Hills so I'm pretty familiar with this area. (Spider Man in the comic goes to Forest Hills High School). If you go to Corona Park, there's Shea Stadium (Yes, the 7 train that John Rocker so famously disparaged). Also in Corona Park is the New York Hall of Science, New York's only hands on science museum. I normally work there on weekends but this weekend I have to give a speech at a PTA sponsored event. Personally I hate my job and I think the place is lame, but it's very close to Shea Stadium so you might as well drop by if you want to visit Shea. If you have time to burn you might want to check out Forest Hills Gardens, it's probably one of the nicest neighborhoods in Queens. (BTW, if you want to visit Forest Hills Gardens, don't take the subway, take the LIRR, the LIRR stop in Forest Hills is right above the gate to the Gardens). BTW, definitely get subway maps, the subway can be extremely confusing if you're new. Oh, and try not to get off the subway anywhere between Manhattan and Forest Hills, some of these areas aren't such nice neighborhoods and can be a bit agressive if you know what I mean [:)].
If you want to see the really bad neighborhoods take the 6 train uptown to southern Bronx (northern Bronx is pretty good). Once I fell asleep on the subway to school, woke up, the subway pulled into a station I've never seen, and suddenly the lights dimmed and we pull into this omnious place. I seriously thought for a second that I'd died and went to hell. I got out and ran like hell downtown. Every 10 feet or so there were chalk figures on the pavement, I don't know if it's street art or murder scenes, but I didn't want to stay around to find out. If you're the adventurous type you might want to check out the chalk marks.
