"If you don't work, you don't eat," English settlers at Jamestown were told. So they toiled — or starved. Nowadays, one needn't dirty one's hands for daily bread, but those seeking togetherness with their food don't require such survival incentive. Every Monday and on most weekends, volunteers grab hoes and rakes and till the urban soil, driven by pure ideals. The small pond and windmill visible from two freeways alerts visitors that there's something different about this neighborhood attraction between Bernal Heights and Portola. In return for an afternoon spent getting closer to Gaia via weeding the garden, farmhands-for-a-day receive the literal fruits of their collective labor.
