While going through my "summer" pics, a majority of them about the urban gardening movement in all of its configurations, I noted this article today about the downside: the city at times getting in the way. There is always a balance between individual contribution and legislatation designed to protect citizenry but that can get in the way when something new and innovative is in process.
From what I have seen so far in Detroit, urban gardening while perhaps not the answer for a major economic shift, is at least a strong source for community effort.
