I recently saw a competition between two teams for Freerunning, which I understand is very similar to Parkour. Very interesting stuff. From an earlier post, is this your SECOND ticket for this practice? If so - maybe you should research the laws govering this activity in your local area before you continue and possibly dig yourself into a huge hole. Maybe if the local law enforcement has some city ordinance against this practice there is a safe (and more legal) location for your activity.
