I belong to a big organization that has monthly meeting with speakers. Authors, editors, agents...last month, Deidre Knight of the Knight Agency gave a great lecture and question/answer session. She also took pitches.
I know of three writers on this board who are members of that organization, too, but they can out themselves.
The big O also has critique group pods around the area, and I attended one of those for a little while, but it didn't really work out for me. After a while, you get to know everyone's themes, you know what they're going to pick out from your work to comment on, and if it's that predictable, then why bother?
Now I meet twice a month with a couple of people (again, both of them are members here, too) and we kinda just chat about markets, goals, books, resources, what have you. Oh, and we eat and I drink waaayyy too much diet coke.
