What about another large Earthship meeting next weekend, like Sunday the 9th?
If we have a big enough room (does anyone have a place to offer? otherwise we could try that same room in Phinney Ridge again) we could have a meeting for an hour or so, then a movie screening (Garbage Warrior or New Solutions) and then have another hour or two for discussion. And depending on who's there and how much people are knowledgeable and/or motivated to get involved, we could dive into planning.
Comment/give feedback now, and we'll schedule within the next couple of days.
