Slacklining [VIDEO]

So I'm not sure you can call Slacklining a sport, but it is amazing what these people do.  I'd call it the combination of a trampoline and tight rope.

I'm not going to lie, the music is kinda wack in this video.  But you can't deny this is pretty amazing.  I don't know if Slacklining is ever going to be in the X-Games but honestly, why the hell not?
