re: I need a MUST DO list of things in SF

Rental car? Just public transit? Can everyone handle lots of walking? Buy a 3 day muni passport if using transit and hit it hard..includes the cable car, street cars, muni rail and buses and will get you to ballpark, Alcatraz departure point, the beach, suturo baths, coit tower, Lombard,pier 39/wharf and whatever else.

I would personally go to the presidio and hike down to marshals beach before driving to Stinson....
