Every child who attended Holly Hall Elementary School's career day last week, didn't officially complete the event until they had blown Glenn Caldwell's horn.
Caldwell, a tractor trailer driver who works for Tipton from Oxford, Pa., was one of the volunteers who brought their vehicle to the school last Wednesday to share the world of work with the kindergarten, first, and second graders. Caldwell invited the children to tour the tractor portion of his tractor/trailer. On their way out of the truck, they got to blow the horn.
