Sometimes the best work parties are the ones that happen unexpectedly. I met Jori and Betsy at the Terlingua Ranch Lodge when I played a show there a couple of nights ago. We got to talking. They told me about their travels across the country on waste veggie oil. They have traveled over 5000 miles by using the grease that restaurants throw out. They spent the last couple of nights camping out at Earth Language and today they helped us finish the foundation of the dome. Their help turned a full work day into half that. We spent the rest of the day hiking and playing an old Yiddish card game called Klabberjass that my grandparents taught me.
To finish the foundation, we filled in the gaps between the bricks with the same materials as the bricks themselves ( 5 parts gravel, 5 parts sand, and two parts cement ).
Here is a link to Jori and Betsy's blog about their travels using grease.
