Four weeks spent at a roadside diner owned by his uncle and aunt give Doug an exciting glimpse of the trucking world. In vivid, on-the-scene passages, in a departure from her previous religious themes, Mildred Luckhardt recounts Doug's adventures from finding a lost truck to getting a bulky trailer out of a disastrously low underpass- so that drivers, trucking, the urgency of efficient delivery and cooking in Uncle Ben's restaurant come very much alive. A valuable book in its illumination of a little exploited subject. Harve Stein's drawings are graphic and pleasing. Cloth binding, reinforced.
