Best of all, they shone like the stars they have become.The 47 students in the Carrera program at Lamar County Activ- ity Center wowed an audience of parents, friends, board members, city officials and others at the program’s luncheon finale last Thursday.On surplus plastic buckets from lunchrooms and hardware stores, the ‘drum line’ made toe-tapping and heart-stirring cadences, as the step dancers proved their expertise at synchronizing stomps and hand-claps.
