I tried an experiment this year (2012) of giving out free CSA shares to low-income people. I got recommendations for four shares, two from one person and two from a community organization called Parent 2 Parent in Bellingham. Of the four shares, one family missed their pickup one day so I cut them off. (They were also problems in other ways.) One person gave up her share because she is on some sort of diet where she eats a lot of mangoes, coconuts and avocados to help with her spiritual quest and couldn't comprehend eating locally and in season. The other two are appreciative.
I advertised for donations both on Local Harvest and through local outlets - any amount appreciated, no matter how small. I have yet to receive even a dime. None of my free shareholders were required to work. I do get some help from the person who recommended two of the shares and she has been a willing worker and is also learning valuable skills.
Another interesting anecdote: A couple of years ago a group in Renton (southern suburb of Seattle) tried setting up a FREE market stand in one of the "food deserts" in Renton. They couldn't even give the food away!
It is amazing is it not?
