Ottawa residents be sure to drop everything to get to tonight's Rideau Valley Roller Girls double-header at Barbara Ann Scott Arena (2250 Torquay Ave). Doors open at 6pm, with the first bout getting under-way at 6:30pm. First up, RVRG's Slaughter Daughters take on the Venus Fly Tramps from Kitchener, then RVRG's Riot Squad battle the Disloyalists from Kingston. There is nothing that you could possibly have on the agenda for this-evening that will be more awesome than an evening of derby. Nothing! Promise.
