Let's face it, we all don't live in the country. There must be thousands of permies and prospective permies who want to grow food and don't have the place to do it.
If you don't have patio or balcony, all your windows face a wall or someone else's apartment, etc, here's a site that can help to direct you to a local community garden, in both urban and rural communities. It seems a good way to find nice people... they can't all be loonies.
Your town doesn't have a community garden? SO, START ONE!
The American Community Garden Association (ACGA) can help you to find a garden or even to start one in your town.
"ACGA and its member organizations work to promote and support all aspects of community food and ornamental gardening, urban forestry, preservation and management of open space, and integrated planning and management of developing urban and rural lands."
That's a big deal and you can help.
One of their books that looks extremely useful for such an endeavor is Growing Communities: How to Build Community Through Community Gardening by Jeanette Abi-Nader, David Buckley, Kendall Dunnigan and Kristen Markley.
