Cordwood Building

I'm looking to enrich myself, to learn things that I feel important for the future. Checking out Earthwood Building School and their cordwood building classes. Seems like it could be an interesting endeavor to build with cordwood but I have many questions. There may be classes I could take that are closer geographically so I'll keep looking but it is an intriguing place and I may have to go at least for a visit someday!
