San Francisco Historic Streetcar on Route Through Dolores Park

Nice!

This isn't the service route for the vintage streetcars --- they use those tracks to get from the rail house to their normal Market/Embarcadero route. But you can still ride them, kind of a Muni "secret menu." Easy way to find them is to use an app/website with realtime locations and look for an F streetcar that's on the wrong tracks.
