Man enough for roller derby, that is? Now that the resurgence of women's roller derby has reached critical mass (you know you're playing an established sport when Drew Barrymore makes a movie about it), the Rose City Rollers are letting the boys into their tree house. Tonight is the first men's derby bout in Oregon, and it's not to late to sign up! You have until the 7 pm pre-bout meeting at which they will give you the basic rundown and then turn you loose on each other (all the nitty gritty deets are here). If you just wanna watch this historic event, roll up to the Oaks Park roller rink with $5 at 8 pm—there won't be concessions, though, so bring your own snacks!
