And this isn't going to be an easy match, they're taking on the Breakneck Betties from Portland, those chicks are badass. Doors are at 5 with the Hellgate Hellions junior league starting at 5:30. The main event starts at 7 p.m. with The Cigarette Girls Burlesque performing a family friendly half time show. (Family friendly, DARN!)

As always, tickets are $10 at the gate and kids 12 and under are free.

Not familiar with derby, or maybe you have attended but didn't get it? Here's a short but helpful video.
