The thread that got InOBU started was this one: Help: Seeking good acoustic venues in NYC. It's about NYC venues, with some reference to the NY Pinewoods Folk Music Club among them.

Pinewoods Camp is in Massachusetts, run by the Country Dance and Song Society, and has a wonderful Folk Music Week, along with an early music week and numerous dance weeks. Check the information on "Programs" here. As Joy said, the NY club was started by folks who enjoyed the Folk Music Week experience.
