sandra215 asked «What about the car? Should we take the car to a garage?»
Although I wouldn't take the car to a garage, there are other options. I would use the car to follow th 49-mile Scenic Drive signs. There are two maps of it on The FLAG/MAPS page geocities.com/touringsfo/…FlagMaps.html has links to the best on-line MAP of San Francisco, the outstanding WALKER/BICYCLIST map that shows the steepness of our streets. The new version of the formerly superb map created for the San Francisco Municipal Railway has removed many streets' names making it less useful. It's cluttered with our many bus, cable car, street car, and bus routes. There is also a map of our CABLE CAR ROUTES, our 49-mile SCENIC DRIVE, and a superb map of GOLDEN GATE PARK.
I'm preparing a written description of the route but it's not finished.
«or are there other options?»
Also on that page is information about our excellent public transportation.
