Nearly every attraction in San Francisco offers a senior discount; age requirements vary, and specific prices are listed in chapter 7. Public transportation and movie theaters also have reduced rates. Don't be shy about asking for discounts, but always carry some kind of identification, such as a driver's license, that shows your date of birth.
