I ran across the work of Russell Libby a few years back when I was writing about the Food Safety Modernization Act. The Common Ground Country Fair in Maine was produced/ or is produced by a man I met at the AAAS Conference a few years back.
He was one of the seed planters in a shared pot of beets that I have written about.
Glad to run into this talk, and this most delightful yearly event held in Maine.
