Design details and budgets? Government is cocking it up already here! Love from Chile, Grifen PS You can help by making donations at the Permaculture Research Institute. We need 50 or so of you to donate a grand and we are set to make a huge difference here. Whenever you are in Chile my hospitality is yours. Please forward this to other appropriate lists.
