Cable Cars

The San Francisco cable car system is apparently the world’s last manually operated cable car system [wiki]. Of the 23 lines established between 1873 and 1890, only 3 remain: two routes from downtown near Union Square to Fisherman’s Wharf, and a third route along California Street. While the cable cars are used to a certain extent by commuters, the vast majority of their 7 million annual passengers are tourists – including myself :)
