Add this to my list of favorites: Museum of Modern Art. It was really awesome. If you are ever in NYC, go Friday after 4, because it's free. It was a bit crowded, but we had plenty of time to see everything we wanted to see. And you get to see paintings by a lot of really famous artists (Picasso, Matisse, Warhol, Lichtenstein, et al).
This is also one of my favorite pictures I took in NYC. More pictures to come.
