A few years have passed since I posted this topic, and I have to say, I've come to realize that there are lots of people ACTUALLY doing permaculture, all over the place. They aren't necessarily on camera, but they're definitely out there doing the good work that needs to be done.
A lot of the work I have seen first hand is at Dancing Rabbit Eco-Village, where I am now a member! If you're interested, check us out at www.dancingrabbit.org
I am most impressed with Geoff Lawton and some of the people he has showcased in the video series he and his comrades have produced in connection with their online PDC project. I definitely recommend checking that out.
Thanks for taking so much interest in the topic and keep growing the greens!
