Arch Rival Roller Girls/St. Louis Gatekeepers

The Arch Rival Roller Girls keep going strong after a decade of bumps and hits on the track. The ladies' flat-track roller-derby team meets up with the men of the St. Louis Gatekeepers for a two-fer starting at 6:30 p.m. tonight at Midwest Sport Hockey at Queeny Park (570 Weidman Road, Ballwin; www.archrivalrollergirls.com). The men open the night, as the Central West Friends challenge the Creve Coroners. In the back half of the night, the M-80s take on the Stunt Devils. Admission is $10 for both bouts, but free for kids ten and younger.
