Flat track roller derby is a fast-paced contact team sport that requires speed, strategy and athleticism. The bout will be a hard-hitting event. The Shanghaied Roller Dolls battle the Storm City Roller Girls of Clark County, Wash., in a competition that will send one team home nursing its wounds. The dolls will donate 50 percent of bout proceeds to CAA, a nonprofit organization dedicated to supporting Clatsop County Animal Shelters homeless pets.
