Where in Northern CA are you? I'm up in Humboldt and there is a
Permaculture Guild but they really don't seem all that interested in branching out with more than one event per year, but a group of us are working on building the
permie community. We're holding a
PDC this spring that will run one weekend per month from April to November, about 100 hours total. If you're in our neck of the woods, reach out to me on here!
