The phenomena known as Parkour has been catching on like crazy lately [ read Jim Munroe’s article from Spacing Spring/Summer 2004 issue ]. It can be easily explained as extreme jogging — but instead of sticking to the sidewalk, you run over cars, fences, even entire buidlings. I was forwarded an 8-minute Parkour film [ streamed on Google video ] shot in Russia that shows a young guy running around, through, and over his town. The buildings are burnt-out and abandoned, the infrastructure is crumbling, but the Russian tracuer (what they call a parkour participant) has turned this city into an urban gymnasium.
