Strap on your skates and pads and don’t forget your helmet or your nickname. Roller Derby is back and faster than ever. We’ll spend this hour with Melissa “Melicious” Joulwan, founding member of the Texas Rollergirls and author of the new book “ROLLERGIRL: True Tales from the Track” (Touchstone, 2007). We’ll also be joined by Antera Tinoco, AKA “Gata Killya” of Assassination City Roller Derby in Dallas.
