Bank of America is offering it’s customers free admission to local museums all over the country. It is usually the first full weekend of the month and you just have to present your bank card at the door.
We have been to Museum of Discovery and Science with the program. Basically it means the adults are free (as long as you have a bank card for each person) and you just have to pay for the kids if they are over 2.
