One sure sign it’s Sunday in Baltimore is the sweet sound of revving dirt bikes as Baltimore’s Twelve O’Clock Boyz wheelie their way through the city streets. It’s a classically Baltimore conundrum: the bikes are illegal, but, after a fatal high-speed crash a number of years ago, police aren’t allowed to pursue them, either. The Twelve O’Clock Boyz themselves have been both condemned as a gang and lauded as an informal social-support organization in a city without many other options, especially now that rec centers are closing down due to budget crunches. So, who are these dirt bikers of Baltimore? Heroes or villains? Criminals or mentors?
