If you have a Bank of America or Merrill Lynch credit or debit card, you can get free admission to participating museums. Each cardholder gets one free general admission to over 150 museums around the nation.
The deal is good for the first full weekend of every month. That means you can take advantage of the Museums on Us program this weekend.
In Tucson, you can get in free to the Tucson Museum of Art. If you happen to be going to Phoenix, you can get into the Phoenix Art Museum or the Children's Museum Phoenix for free.
