The first dates are Jan. 2 & 3. You’ll need to present a photo ID and your Bank of America card.

For example, the Birch Aquarium at Scripts is included in San Deigo, CA.
Another way to get free admission is to check out a Culture Pass at one of the local libraries. This program covers a number of museums in the area, plus the Phoenix Zoo and Desert Botanical Garden.
