ABF is a season-long beneficiary of the Minnesota RollerGirls bouts.
You can sign up to volunteer at the bouts here - staff the ABF table before the event and during half time, and of course feel free to watch the bout! Season 15 started in October 2018, and there will be one event per month. You can sign up for one or more!
The next bout ( "Survival of the Fastest") is on February 23.
