The above video is a Parkour practitioner's view and includes mashed up images of both Roosevelt Island and NYC's Central Park. For someone not used to quick camera work this video might be a bit strange to get used to but is quite interesting. I recognize shot outside Rivercross, behind Westview, along Island House among others. The last minute or so is a bit of out takes and just walking around.
As I have stated in past posts about Parkour, the actions taken would not be sanctioned by PSD and this video is not disagreeing that many of the moves seen could be dangerous.
