Everytime I see videos like this it makes me want to get involved in some extreme sport. :lol
7 years ago there was a Russian free running video with some guy running through and across the tops of abandoned buildings in the city. It had me and my brother jumping on dumpsters and climbing buildings trying to be free runners. :lol
Well he did the stunts, I filmed. :lol I didnt have the balls. Plus I broke two toes in my left foot at work, so I couldnt and wasnt doing any kind of running for 3 months. :lol
