Sure, you could build elaborate shade structures and host impromptu lunch parties to enliven the City Hall plaza, or you could just invite a giant, dancing kidney bean. Shawn Williams, Mayor Mike Rawlings' social media guru, was kind enough to pass along a couple of pics of said kidney bean, ahem Billy the Kidney. There were no action shots -- for that you should check out Morning News photog G.J. McCarthy's excellent pic -- but they are pictures of a giant kidney bean. At City Hall. Mingling with your elected leaders.
