Giant dinosaurs. And the rest of the museum is great if you also like giant whales and outer space and especially the life size dioramas of animals and cave people, which might be the very best Art in all of the city. Sigh.
Its an image imprinted in everybody's mind: the background for hundreds of movies, ads and commercials. Actually standing on a saturday-night at Time Square, hearing dozens of different languages of tourists around you, and being fully emerged with the sounds and light, slightly frantic and crazy… You are in NY.
Its quite a trip out there but so very worth it if you wanna have the very special beach-experience! You can go there by car and then take the ferry either to Pines or Cherry Grove (I would prefer Pines!) or you do all by public transportation - there a "getaway tickes" for 36Dollars and the transfer works really smooth - may even be faster than by car!
As Jim Jarmusch put it in the documentary Blank City, the address is roughly between Bowery, Avenue B, 14th Street and Houston. This area of the city is steeped in art, film, and music history; so many hugely influential artists, film makers, and musicians still live and work here. For such a small area, I think it's had more concentrated influence on contemporary art and culture than anywhere else.
