“We end up in a ladies’ basketball team. Learning to play, we trained with USC’s basketball team. Pros play for one hour, but we trained in 20 hour days. Brooke needed an icing unit. My knee got twisted. I had to have fluid removed, and now there’s no ACL ligament in it. It was really tough, but at least I can definitely make a basket. I almost can’t miss one.

“Today I have a hoop in my backyard. Being athletic, I did my own stunts. But it was so difficult. I didn’t understand why we had to train so hard.”

Activist Daryl’s “been arrested for disobedience five times. To save farmers. And bring awareness to Appalachia, where mountaintops get blown away to get at coal. And three times for fracking’s stupidity of putting our largest water reservoirs in danger.

“Our world’s changed. Spending big money, corporations have bigger say nowadays than citizens. No more by the people for the people. It’s now by the corporations for the corporations.
