Vibration Urbaines – October 26th Posted on October 18, 2013 by Effraim — Leave comments ↓ October 26th is one crazy date for flatland contests! Not only the World Circuit and the Guru Jam, but there is the Vibration Urbaines contest in Pessac (near Bordeaux, Gironde, France). Thanks to Jimmy Biondi for heads up on this one.
