There are a lot of reasons why living in San Francisco is so great, but if you’re into science and live in Chinatown, Russian Hill, Nob Hill, Telegraph Hill, North Beach or the Marina then you’re in for a special treat this weekend courtesy of the California Academy of Sciences.

From September 16th through September 18th, the California Academy of Sciences will be offering free admission to residents of the aforementioned San Francisco neighborhood to check out all the awesome exhibits, critters and creatures.

Adults must have photo ID with proof of address. Check out the site for more details.
