One of my favorite things about San Francisco is the trams. Nope, not the cable cars, but the old, restored streetcars that run along the F line. Maybe it's because I spent a couple of years as a kid in Brussels where the trams still run strong.
There is something nostalgic and very cool about seeing the various styles, hearing the traditional noises, and actually sitting on real wood.
In San Francisco, there are up to 20 that run along Market Street and the Embarcadero.
They may not be the most efficient or comfortable method of transportation, but they certainly bring back a bit of history.
