Hi Miles !
There are people riding around in Paris. There is the famous « Tuesday evening ride », but it is not trial street, although, you can join us anyway.
The meeting is at the « Fontaine des Innocents » in Chatelet les Halles. Somme people do ride trial before the meeting. Send a private message to okux, and he will tell you where they meet. I am sending this by email too to make sure you get it !
