Freestyle motocross, or FMX, is already pretty nutty. It's a variation on regular motocross racing that shifts the focus away from speed and onto crazy stunts and jumps (think X Games and musician Pink's husband, rider Carey Hart, with his infamous motorcycle backflip). Now, as if it wasn't extreme enough, a bunch of top riders have created "theatrical" motocross. I mean, why NOT add frontflips, pyrotechnics, acrobats, stilt walkers, and fire-breathing girls to the show? I'm thinkin' it takes a lot of BALLZ to be one of the Cowboyz. And yeah, that's ballz with a z. (Tacoma Dome, 2727 East D St, Tacoma, 800-745-3000. 7:30 pm, $20–$55, all ages.)
