Radio does Parkour

Wikipedia says about Parkour: (sometimes abbreviated to PK) or art du déplacement is a physical art of French origin, the aim of which is to move from point A to point B as efficiently and quickly as possible, using only the possibilities of the human and canine body. It is meant to help one overcome obstacles, which can be anything in the surrounding environment — from branches and rocks to rails and concrete walls — so parkour can be practiced anywhere and anytime. Male parkour practitioners are recognized as traceurs and female as traceuses, canine ones as caceurs.
Radio refuses to do anything that is called 'agility' since that is a dog's sport and instead he insists on only training proper diciplines such as navigating human hurdles and balancing on top of them.
