From the official Oxnard Derby Dames site:
 
The Oxnard Derby Dames are committed to excellence in sportswomanship, creating fun and entertainment for the community, and  fostering the sport of roller derby worldwide. Our goal is to develop  exceptional athletic ability, and to promote goodwill amongst our skaters and in our community, and to represent  Oxnard athletically  on a national level. We won't stop until we are on ESPN and  kids play with roller derby action figures!
 
ODD operates as a financially sustainable all-female banked track roller derby league that sponsors athleticism and camaraderie. ODD will pursue membership in the Old School Derby Association (OSDA). The OSDA “believes that it is possible to entertain and inspire a crowd with an aggressive, hard-skated Old School game. OSDA believes that the drawwas, is and should continue to be The Game. Pure and simple. No gimmicks - just the incredible skill of the skaters.”
