The corner of Washington Park and Dekalb Avenue has been the place for upstate farmers to sell their wares for some time. But increasingly the site is playing host to tables of another kind. For at least the second week in a row, the Obama campaign has doled out cookies in exchange for campaign donations, and today we spotted a group called Fort Greene for Peace handing out flyers to protest the war. Looks like the farmer’s market is becoming the neighborhood’s public square. Maybe we’ll see people giving speeches on soap boxes there soon.
