I finally looked up the ICP - International Center for Photography. I don't know pros and cons on the place at all - but I'm a Magnum Blog follower to some extent, and if I were nearby and knew about it, I'd go in...

Me, I like smallish galleries that show photos, and I've seen some wonderful shows. I dragged a2kers to one in San Francisco, which I remember most for having a few a2kers arguing in the hall and some others gallery roaming. That was some time before some of us gathered at the coppola cafe, I forget the name of it.
During the first a2k meet in Chicago, a near horde of us went through the art museum, some assertively individually, like walter, rjb, me, eva, and some as a group, which I think JPB led, since she knows the museum well. I ended up in the basement with a photo show that knocked my socks... before getting back to the group.
I know from nothing about the New York Met photo collection, but I figure they have a good one.
