Those of you who know how I feel about garden thieves (I'll post more on this another day) are going to think I've lost my mind, but I just love the idea behind Fallen Fruit. The idea was to create a map of "public fruit" in Los Angeles--fruit growing in public spaces and also fruit planted on private property that overhangs a public space. They publish maps and put out "Fruit Alerts" to let people know when, say, the avocados are ripe.
And they encourage people to plant fruit trees close to the road. Share the bounty.
Most of LA was once an orchard. I like the idea of it returning to orchard, in a subversive way.
