Hayes Valley Farm is a community-run farm on a former freeway in the middle of San Francisco. The land was slated for condo development but the plan was put off when the economy slumped. Out of the ashes of that dream arose a utopia of a different sort; a suspended reality where fruit trees are grown on what was once a freeway on-ramp choked with cars. Now there are flowers growing out of the double yellow lines, and constant opportunities for children and adults to learn how to grow food and to get dirty doing it. Although the farm has only an "interim use" permit, meaning that it can't last forever, farmers Zoey Kroll and Jay Rosenberg know that the enduring harvest of this project--the truth that even the most outlandish-sounding things are possible if we make them so--will far outlive the farm itself.
