I did my PDC with Kareen and Jesse last summer and it was an incredibly fun and informative 14 days. They're both very plugged into the permaculture community in Montana so the site visits were really awesome. We had a chance to visit Sage Mountain (where this year's PDC is) and I must say that it's so awesome that my wife and I half-joked about doing our PDC again this year just to be able to stay there!
I can't say enough great things about the experience and the quality of the instruction that we received. And both Kareen and Jesse went out of their way to answer questions and share knowledge outside of the structured sessions, which is something I in particular really enjoyed.
