I took the high-speed rail from Florence back to Rome this morning, cruising through the rolling hills and expansive green landscapes of Tuscany. As soon as we pulled into Termini, I could feel the pulse of this city. There's an energy to Rome that's much more intense than a place like Florence can offer. This is a capital city, a center of politics and commerce and media. There's an almost palpable buzz one can feel in the air, not unlike what you experience when you arrive in the middle of New York City.
