So, the guys in sales were trying to describe it to us the other day - telling us all about the Nuclear Cowboyz FMX tribes, the Soldiers of Havoc and the Metal Mulisha, who return to the Tacoma Dome this weekend for an action-packed show set in the war-torn city of Los Angeles during the year 2150. 

Or something.

From what we're told, the motorcycle tale unfolds as the two tribes' survival is threatened and besieged by an evil force, The Tempest, and her "electrifying" Cyborg Army.

Again, this is the dudes in sales talking.

On top of all this, we're told, the Nuclear Cowgirlz are catapulted into the heart pounding fury and frenzied excitement, whose allegiance to their tribes only intensifies the Tempest's rage to destroy the Nuclear Cowboyz. Naturally, the Soldiers of Havoc and the Metal Mulisha's battle is fought through fearless freestyle gravity defying stunts, combined with outrageous pyrotechnic and laser displays synchronized to heavy metal, rock alternative and electronic dubstep music.

Got it?

As for the cast of characters, we're told the Nuclear Cowboyz 2012 has assembled a great cast of freestyle motocross, trials and quad riders, including recent X Games 17 medalists Ronnie Faisst, Adam Jones, Mike Mason and Winter X Games medalist Caleb Moore.
