If you live in a bigger community, you might do a search and see if your area or an area near you has a food forest. I am not sure if it is just a hippie washington thing but we have a few food forests here. Designed as permeaculture with native edible plants, bushes, and trees - it is designed to be for anyone in the community to come and take whatever they need. Here is an example of one in Seattle. it's a super cool project.
