In the spirit of Smithsonian Museums, who offer free admission everyday, Museum Day is an annual event hosted by Smithsonian magazine in which participating museums across the country open their doors to anyone presenting a Museum Day Ticket...for free.

Check out the link for a list of Bay Area Museums offering free admission. The beauty of this offer is that it's nation wide so where ever you live, there's probably a museum participating in the program.
