Today we bring you a "Wild Cards" edition of Metro Connection, in which we cast aside our usual thematic approach and bring you stories that are all over the map. We'll get the latest on this week's battle over Metro's new "Silver Line" in northern Virginia. We'll bring you the story of a Washington music luminary who's about to put down his baton after nearly a half-century of choral performances. And we'll dive in to the watery depths of our oceans, which are losing coral at what scientists say is an alarming rate.
