Some girls choose soccer or cheerleading. Ivy Wolk chose roller derby.
"This is it, this is for me," the petite, wide-eyed 9-year-old said to her mom the first time she saw the Los Angeles Derby Dolls hit the track, and one another, two years ago.
Split lips, black eyes, rink rash and bruises are trophies here. "It's not child abuse, it's derby," she once told her mother, who made sure she alerted her daughter's pediatrician about the girl's newfound love for the sport.
"There have literally been days where I have been like, 'I must be crazy.' But she just picks herself up and gets back out there," said her mother, Tracy Wolk.
