The Guerrilla Grafters are a group of rogue artists who roam San Francisco, covertly grafting fruit-tree branches onto ornamental trees to create a municipal free lunch. John Robb calls it "resilient disobedience."
How can you improve the productivity of your community even if the officials are against it?
One way is through resilient disobedience. For example, there's a group of gardeners in San Francisco that are spreading organic graffiti across the city. How? By grafting branches from fruit trees onto ornamental trees that have been planted along sidewalks and in parks.
They are using a very simple tongue in groove splice that's held together with annotated electrical tape. Good luck to them.
