My daughter went to school in North Carolina. For some reason she was supposed to come home by bus with a stop in Baltimore. Visiting a friend or something. I told her to fly, or I'd meet her bus in Baltimore. I used to go to Washington from New York by train or car pretty often. Baltimore always gave me bad feeling. I've already taken a visit to Camden Yards off my bucket list.
Camden Yards is a nice park. I went several years ago. Stay in the tourist area and you should be fine. Though it goes from nice to guest real quick.
