John,
Thanks for posting. The convergence was an awesome gathering!
I live on a suburban-scale lot (1/3
acre) in town, so I've thought a lot about how to include my neighbors, both willing and unwilling
Your neighbors may or may not be reachable in their current state of mind or foggy illusion they live in

But their kids are definitely highly susceptible to the
Permaculture patterning. So at my place, I make sure that the edges of the property are highly interactive with the neighborhood kids. This means food growing along the sidewalk in abundance, places to meander and sit, and dimensions of interest as they peer into your garden.
Here's a few of pics of my place with street side view:
I believe strongly in the "if you build it, they will come". People are like
mice in a maze, if you provide a place to sit, we meet and talk. If you put food on the street, we stop and nibble. Those small connections and conversations are the foundation for neighbors knowing each other, and then the synergies that come from there.
Once we are eating berries together and I give you a jar of my
honey, we can talk about that laurel hedge that's shading my persimmon tree. And then on to more touchy issues of how your GMO corn pollen is polluting my
seed. Good relationships are built on connections over commonalities.
