Kind of late notice, but I thought I would see if anyone is intersted in catching the roller derby bouts this Saturday. First bout is at 4, second at 5:45.
More info here: http://dcrollergirls.com/
Tickets are $12 online (plus ticketmaster fees) or $15 at the door (I think). One admission gets you in for both bouts. There is the usual stadium concessions at the site, but food before or after may not be a bad idea.
