farms in Oakland?

An interesting tableau spotted at Ghost Town Farm, an urban farm in West Oakland.  This half acre or so is located on a decidedly urban corner in a sketchy neighborhood.  The owner is recognized as a leading voice in the national urban farm movement.  She grows vegetables, raises goats and bees, and occasionally has a pop-up market where she sells surplus veggies.  And now she's the center of a surprise controversy related to some obscure and ambiguous regulation about farming within the city limits.  How dispiriting.
