I did read that book. I thought it quite tragic. They forced the man to behave according to the very narrow rules of today's culture. I was bereft for him, and for all of us, that such control of a human being is possible. He was not harming anyone, except those few who would not tolerate someone living outside of norms. I found it interesting that he chose to break into home, even those homes that had left him goodie bags outside.
I love that stone!
You can grow some lettuce inside without the lights, if you have a great big south facing window. I've done that, too.
