One of the constants of Parisian life is riding the Métro, which first opened in 1900 and serves 1.4 billion (!) passengers every year. Le Métro provides wonderful insights into Parisian life. Not surprisingly, its use can bring adventures, ones that affect us directly since, with the exception of one student who lives near the Accent Paris center, we all take the Métro to class. As a result, when the Métro experiences delays, we experience delays. We have learned to check its site for "perturbations," as the RATP (Régie Autonome des Transports Parisiens) provides – "en temps réel" – information on delays due to mechanical breakdowns, passenger injury, suspicious packages, and strikes.
