I'm in Wilmington, MA. Starting to do some stuff in the backyard (raised beds, hugel, fruits/nuts, compost, rain harvest). There's a Boston permie meetup http://www.meetup.com/Boston-Permaculture/ and a North Shore one http://www.meetup.com/Northshore-Permaculture-Meetup-Group/
What kind of things are you interested in?
