For those of you in the NY area, I think it'd be nice to stop by the MOMA for the Henri Cartier-Bresson exhibit. I believe it just started, and you have until July.
Tip- The MOMA is free for students, so dig up your old college ID card and bring it there.
Edit- Nevermind, I guess I was too young the last time I went. It's not free, but you get a discount. Still, the Cartier-Bresson exhibit should be nice.
