There is such a Parkour group in Palm Beach. Palm Beach Parkour or P.B.P. Im one of the members. We are based around Palm beach County itself, I research new spots and look for them so the members can go and parkour. There's no price in joining, but we are working hard to promote parkour and make it be seen by the people that live in our playground.
Want more info let me know you may be able to join. But just maybe.
