Given half a chance, I would most certainly grow my own foods again.  At one time, I had a vegetable garden which I shared with all the neighbors.  Unfortunately, I never learned the art of canning.  Currently I'm restricted to a modest and unprotected (from the critters)herb garden. We do shop at the local farmers' markets for fresh foods.  There have been several articles in the paper about schools setting aside a bit of land for the children to work, learn and grow food.  There are also a few sections of abandoned properties that have become "collectives", where all of the local residents participate in the cleanup, planting and harvesting. Many take the bounty home to feed their familes and much is donated to local food banks.
