I was lucky enough to visit San Francisco the other month-- and oh, what a wonderful city! The very best, though, are those cable cars-- worth the hype and more! Everyone should visit the city, and take a ride.
The title, by the way, is a reference to the song "I Left My Heart in San Francisco" by Tony Bennett: "where little cable cars climb halfway to the stars..."
These photos of cable cars are from 1947; only the people aboard look different today!

They push it manually while it turns-- even today! Source
