Please direct me if this is listed somewhere else, but I have not been able to find this anywhere on Permies or elsewhere, but...wouldn't it be great if we had all of the Permaculture Design Courses for the Pacific Northwest (and all other regions too) listed here on the forums.
So far I have:
alderleaf wilderness college: http://www.wildernesscollege.com/permaculture-courses.html
Gaiacraft in Southern BC: http://www.gaiacraft.com/gaiacraft-courses/category/permaculture-design-certifications
Northwest Permaculture Convergence: http://northwestpermaculture.org/content/two-week-residential-intensive-permaculture-design-course-may-23-june-7-heartsong-retreat
Southern Oregon Permaculture Institute: http://www.sopermaculture.org/SOPI/Courses.html
Siskiyou Permaculture: http://siskiyoupermaculture.com
Lost Valley in OR: http://lostvalley.org/intern-pdc-track/

And I'm sure there's plenty more out there, so please add any you know!
