Each San Francisco neighborhood (defined by zipcode) can visit the California Academy of Sciences for free over a three-day weekend (Friday, Saturday, or Sunday) in the spring and fall of each year.

So that means as long as you have a driver’s license or other proof of residency, you can save yourself $35.95 and visit the museum for free. Read the full rules.

The Rules: Each visiting adult must show a valid photo ID with proof of residency (you may not bring out of town guests for free; they still have to pay). Visiting adults are limited to six children for free entry.

The following items or combinations are acceptable:

• A driver’s license or state ID card
• Photo ID plus postmarked envelope, postcard, or magazine label with name and date
• Photo ID plus utility bill (gas/electric/cable), bank statement, or letter from a government agency with name and home address (not a P.O. Box)
