A metal skatepark with many flat walls to paint. Fair amount of competition for the best walls, but it's not too bad. WARNING: due to the numbers of little kids you will gather an audience and they will drive you mad.
Proper legal wall near the train tracks that run alongside the park. Careful though because the bridge isn't actually legal
Bridge over the train tracks is permission only, the other wall nearby is free for all.
Is this wall still safe to paint?
