Not in Seattle, of course, but a very interesting permaculture course...only about 3.5 hrs. away from Seattle...
Learn to observe the site; integrate with existing plants, trees, and natural features; set up an initial keyline-type farm path pattern for irrigation, and design & build a food forest on a slope.
Cost: $250 includes up to 2 nights camping and organic vegetarian meals.
