If you've got a Bank of America card and some spare time on the first weekend of any month, you can take advantage of free admission to any of 120 participating museums, zoos, aquariums, and other cultural and educational institutions.
After 12 years, the Museums on Us program has expanded its reach to 74 cities in 27 states. It's useful whether you're staying around town or on vacation, and is good for general admission at places like the Metropolitan Museum of Art in New York and the Shedd Aquarium in Chicago.
The first weekend of the new season of the program is May 2 and 3. I'm already planning my free museum day.
