For a great, cheap day of sightseeing:

Pack a picnic lunch from items from a grocery store.

Rent or borrow a bicycle at the wharf. Ride it across the Golden Gate Bridge into Sausalito.

Read up on and take reasonable precautions when locking up the bike.

Bum around Sausalito and take the ferry back. Good times.

Reminds me of great day getting a subway sandwich and watching the America's Cup practice sailing from the battlements of Ft Point underneath the GG bridge. Watch out for the seagulls.
