You've probably heard about the Dark River Derby Coalition, Quincy's all-women's roller derby team. The group was created in 2010 and played their first bout in 2011. The next DRDC home event will be on July 13 at Scotties Fun Spot. Even though you may have heard of the Dark River Derby Coalition, you might not be sure exactly what roller derby is. In order to get you good information, we went to the Dark River Derby Coalition's website for all the basics of roller derby.
