Apparently I've been living under a rock as a traceur, because I've never heard of this version of Parkour, despite it's apparent media attention. It's been aptly and cleverly named The Lying Down Game.
As the participant, your objective is to go out into public--"the more public the better", according to the creators of the game--and lay face down in any location that permits the human body to do so. They're calling it Parkour, only without the dangers of athleticism.
While hilarious and admittedly innovative, this just depresses me. It originated in the UK, but I see no reason why it won't be making its way over to the US, if it hasn't already. This game is a perfect excuse for sedentary Americans to live their sedentary lives, while still managing to squeeze some undeserved 15 minutes of fame out of innocent bystanders. Why actually improve yourself physically and mentally when you can lay face first on the ground like a moron, right?
Then again... maybe it's not so bad after all >.>
