I was downtown running some errands today, when I came across a whole bunch of people sitting in front of l'Hôtel de Ville. At first I thought maybe it was another protest, but as I got closer, I saw they were watching a big screen TV:
Tuns out it's an event called "Roland Garros dans la Ville", or "Roland Garos in the City". Besides the big screen where you could watch the matches live, they also had a tennis court where you could watch professional players, sign up to play a match yourself, or even get a intro-to-tennis lesson. There was also a smaller court for kids to practice and some nets set up where you could just practice hitting.

The event runs from Saturday, May 30 to Sunday, May 7. Hours: 12-7:30pm daily. For more info, check out their website (in English and in French) here.
