So we took this pretty awesome free parkour open gym thing on Saturday and it was as awesome as I thought it was going to be.  Sadly though, they did not teach us flips.  :)  Parkour was invented by this French fireman so that if anyone was trapped in a building or something like that, he could be able to climb walls or do things that normal people would usually be able to do without a ton of practice.  The definition of parkour is: transporting yourself from any point to any point as quickly, safely, and efficiently as possible.  He then taught parkour to his 8'th grade son.  His son turned parkour into free-running.  Free-running is all those flips and twists and things like that while parkour is a much less fancy version of free-running.  But it still looks cool.  So I definitely want to start learning parkour now!  :)
