Both Olson and Simpson insisted they feel totally accepted by the male drivers. These women are paving the way for the next generation, such as 14-year-old rising star, Cassie Berry, known as "Demolition Diva." Berry drives free-style with Olson's boys.
"My dad has a pro mud car and I've been around that since I was real little," Berry said. "Being with the boys it makes you step it up a notch and get yourself going so you can show yourself and what you can do, and so you can show everybody else."
And she seem to look up to Olson for the blueprint, not just for a career -- how to get the right endorsements and make a living in this rough and tumble life -- but also how to have a life and a family. So whether Berry ends up driving a monster truck or a carpool or both, she'll be crushing it.
