Heading off to Cal Earth in Hesperia, California on Sunday. Bill and Becky Wilson and myself will be teaching the full Permaculture Design Certificate course after a four day romp in the clay and sand of Cal Earth building a super adobe (earhbag) building at the place where it all started through architect Nadir Khalili. For those of you who do not know about Cal Earth take a look at the following video. Will keep you all posted on all developments.
