Crossing guard Valerie Williams plays with Crystal River Primary fifth-grader Kevin Veltman before class Monday. Williams keeps an eye on many of the kids who arrive early. "If they're here before the bell rings, I play catch with them. If they don't have on jackets, I ask them why and I tell them to . . . (make sure to) dress for the weather," Williams said. "Sometimes they want to stay out here when the bell rings, but I say no, you've got to go, but I love them."
