NEW ORLEANS—It’s the running of the bulls, New Orleans style.

Hundreds of men, women and children, most in white with red scarves around their waists and red bandannas around their necks, gathered outside a French Quarter bar Saturday morning to be chased down Bourbon Street by members of New Orleans’ roller derby league.

“Roller skates and a stampede through the Quarter — what could possibly go wrong?” said accountant Jason Medonia.

The run, in its second year, featured 33 roller girls in horned helmets from teams with names like Confederacy of Punches and Crescent Wenches.
