One of my favorite photographers, Emmet Gowin will be giving a lecture on Wednesday, March 24th at 7pm. He was a student of Harry Callahan's who also has a show at the museum until July 3, 2010.
I find their website a little hard to navigate, but if you look through the lectures and exhibitions you'll find both, and you can get the tickets online.
I have a ticket for the lecture, and if anyone else plans to get let me know, maybe we can meet a little early, you know, by ditching work and family obligations for an evening, and take in the Callahan show, too!! Here's a link to the museum;
