Gonbechan - An earthship in Japan. Not sure if there are many around. Yes, planning could be a challenge, as it was in the States.
ZN - Maybe I should put some silver coins behind the wall and engrave them with e.g. “ZN” or “Nail gun Girl”. haha
But, I think the only ritual in our time might be opening or closing a valve.
Eric - Thanks.
And very good observation re. the mortar! Yes, using mortar between the rocks. Still have another day or so to do, then will put the water tank in place and run the pipes.
Also about rocks, a Japanese friend wrote a book about rock walls in Japan and gave me a copy recently. Never thought I’d be interested, but they are growing on me, not falling on me.
