They're also the only Baltimore attractions participating in Bank of America's Museums on Us program, which gains you FREE admission on the first weekend of each month throughout 2011.
The only requirement is that you are a Bank of America or Merrill Lynch cardholder. Just show your card and ID and entry is FREE!
More than 150 museums nationwide are participating, so keep this deal in mind when travelling!
Thanks to our friends at (cool) progeny for the tip-off!
