Trams in San Francisco are more than 100 years old. Now, they have only remained a tourist attraction than a public transport system. The funniest things to see on the roads of the city are buses that run on electricity. Funny because they look like any normal bus but they draw power from power lines similar to electric trains, These power lines are seen everywhere in the city area and makes the downtown look like a mess. Unfortunately I don't have a picture of these buses.
