SF:              There's usually plenty of street parking, within a half block. 
                    On weekend mornings you might need to park a block away. 
                    Parking is a bit tighter on big event days (Bay to Breakers, Outside Lands, Hardly Strictly Blues Festival, etc...)
                    Driving across Golden Gate Park from the Sunset can be problematic on Golden Gate Park big event days
            `           (Outside Lands, Hardly Strictly Blues Festival, etc...).
                        19th is usually the way to go on these days, and leave some extra time....
                    The 31 Bus stops right outside the classroom.
