I'm looking into a Waldorf conference that is supposed to take place this Spring at the Living Prairie Learning Farm near Lincoln Nebraska. It was cancelled this Fall because of September 11. The conference is a Waldorf one.
Some of the folks in the Waldorf discussion list I subscribe to have been discussing conferences including east coast ones and one in Toronto that sounds good. You might try www.waldorfworld.net.
I think they often get Barbara Dewey and /or Rahima Baldwin Darcy to come and speak. (Barbara Dewey is a nationally-renowned consultant who does Waldorf without Walls. Rahima Baldwin Darcy wrote "You are Your Child's First Teacher")
