Marria Grace (right) and her Boston Hoop Troop did their part to light up the Circus-Circus Pep Rally at the Milky Way. The hula-hoopers joined a lion-tamer, tightrope walker, and bearded lady, to name a few of the costumed partygoers, to kick off the 2009 season of the Boston Derby Dames. The league's first roller derby matchup is Feb. 28 at the Shriners Auditorium in Wilmington.
