"I'm Big Joe. 58. Long-haul trucker. Been driving 18-wheelers for 34 years. Sleep in my cab. Eat at truck stops. Talk on CB radio to stay awake. Lonely job. But someone's gotta move America's stuff. Two years ago, I'm driving through Nebraska. 2 a.m. See a car pulled over. Hazards on. Woman standing outside. Looking scared. I pulled over. She backed away when she saw me. I'm 6'4", 280 pounds, covered in tattoos. I get it. "Ma'am, I'm not stopping to hurt you. I'm stopping to help. What's wrong?" Her car died. Phone dead. She'd been there three hours. Nobody stopped. "Where you headed?" "Hospital. Omaha. My daughter's in emergency surgery. I have to get there." No hesitation. "Get in. I'll take you." "In your truck?" "Safest vehicle on this highway." She hesitated. Then got in. Drove her 60 miles out of my way. Got her there in time. She hugged me hard. "Nobody stops anymore," she cried. "Thank you for seeing me." Got back on the road. Couldn't stop thinking about it. Got on the CB. Told other truckers. "We see everything out here. We should do something." Started a code. "Code Angel" we call it. When truckers see someone broken down, stranded, in trouble, we stop. We help. Word spread. Truckers across the country joined. Last year, we helped 1,200 people. Dead batteries. Out of gas. Medical emergencies. Domestic violence victims escaping. Runaways needing safe transport to shelters. We've got a network now. Truckers, CB radio, truck stops. Someone needs help? We mobilize. Saved six lives last year. People broken down in dangerous spots. Diabetics in crisis. A kidnapping victim we spotted and reported. But here's my favorite story. Last month, I'm at a truck stop. Young kid approaches me. Maybe 19. Scared. "Are you Big Joe?" "Yeah." "You know how to ride in a truck?" His eyes filled. "You'd help me?" "That's what we do."...
