A local school district’s buses are back up and running, after a major disruption. Vandals deflated nearly all of the tires on the Trussville City School buses. Friday morning, transportation managers realized the buses had been targeted by vandals, putting them out of commission. "It was a major disruption to our schedule today obviously, and to parents’ schedules. And that we had to call in man power from Jefferson County," Trussville City Schools Spokesperson, Kelly Bowels said .
