As Mike Zint, still Occupying the Post Office exterior as a member of First They Came for the Homeless, put it on their Facebook page:
We have a pumpkin patch here at the Berkeley Post Office community garden. The post office has already removed food crops once, but we will replant. Most people don’t understand the importance of this garden. This is the only community garden on postal property in the country, and it has lasted for 8 months. If this seems minor, try putting a community garden in the commons, and see how long it lasts.
BPOD members Carol and Kathy have been diligently watering the garden, hauling H20 to the site and preventing the drought and the sunny days from shriveling the flora into nothingness.
