Easy subway by sissah
Rome has one of the easiest subway systems I've ever encountered. It's two lines, A and B, and they'll take you anywhere you want to go in Rome. Once you buy your ticket (which a lot of people don't do, and if you don't want to fine -- you'll probably not get caught, but if you do, it's a nice little fine), stick it in one of the yellow boxes on the wall. That's how you do everything in Italy -- trains, buses, subway -- get your ticket stamped and hop on the train. You can get your ticket at one of the booths selling newspapers and cigarettes and gum. Still, Rome is a walking city, and you can pretty much see anything you want by foot, but the subway is way easy too.
