re: Bringing kids to baseball trip. Washington DC and Baltimore

I am going from DC to Baltimore in April to catch a game. Not going to be there long, going to see Fort McHenry before heading to the game. Will see the Babe Ruth museum since it is very close to the stadium. Edgar Allen Poe's house/museum isn't too far but closed the day we are in town.

Their aquarium is reportedly one of the better ones.
