Greenmount is the king of Baltimore cemeteries, followed by Westminster on Fayette. Mt. Auburn is fantastic for the incredible lack of maintenance (better in the summer when it gets very overgrown). If your ever by Druid Hill park, stop by TV hill. The towers can put on quite a show depending on the weather. Also, don't neglect industrial Baltimore. The steel mill @ Sparrows point is tough to get close to without a boat but South Baltimore around Curtis Bay is amazing in a post-apocalyptic of way.
