I enjoyed the video Boo. They are doing great things there for their community. Water is very scarce in Ca and they have done a great job of collecting and using natural rain water. [ They are taking most of the rain that falls on their neighbors property and using it on their property, but they are using what others waste.] I loved the living fence with grafted trees. We have talked about that idea befor and I am facinated by the possibilitys. I most likely would not have used peach trees because they are so short lived, but still the idea is GREAT. It appeared to me that they were using Dwarf fruit trees in their gardens. That allowed for more variety in a small space. Maybe you can avoid a learning experiance and just steal their ideas.
I am always Happy to steal ideas, I do not like to reinvent the wheel every time. Great video, Thanks for sharing.
Never doubt that a small group of dedicated people can change the world, indeed it is the only thing that ever has.
