I live very close to the Groton School, and have seen the Salgado exhibit twice now. I know this is very late notice, but they are screening "Sebastiao Salgado:Looking Back at You" tonight at 7:15 pm. It's at the DeMenil Gallery on the campus of the school. I won't be able to go tonight, but I thought I would mention it. They have a couple of talks planned for April, and when I find the exact dates, I'll pass along the info. I think I will try to go to one of the talks. I'm not sure if this show is travelling anywhere, but it's up until June.
