Motorized Cable Cars

There are Fun Tours on motorized cable cars in San Francisco. These city tours last for 1 to 2 hours. The tours are to depart from Union Square (near Powell and Geary Streets) and Fisherman’s Wharf (near A. Sabella’s Restaurant). The cars will take tourists around the city and even cross the Golden Gate Bridge to Marin, a city near Sausalito.

At first sight of the top photo, the car looks very much like those usual electric cable cars running on rails, but this one runs on "tyres". There are railings at its sides to protect the tourists from falling off. I like this kind of cars because cool fresh air can rush in while the car is moving.

It is different in Hong Kong. Although most of the buses are air-conditioned, the air inside is not fresh at all because it has been trapped and sealed off. Without choice, all the passengers breathe in and out the same stale air.
