Era 4-H club members and sisters Logan Knabe and Hayley Knabe are fierce competitors with their charolais heifers. Pictured are Logan Knabe, left, and Hayley Knabe of Era High School. Both insist their charolais is the best. Hundreds of Cooke County students showed their projects during the Cooke County Youth Fair. The buyer’s luncheon, United Way photo and the premium sale will cap off the fair today.
