David S. Madden of Madden Contracting Company in Mindon, Louisiana called the 2005 Advanced Customer Schools a "slam dunk". Mr. Madden cited Rick Worth's hands-on trunnion adjustment and maintenance class as one of the highlights. Other highlights include the controls class on basic electrical and variable frequency drives by Controls Service Technician Albert Covington as well as the baghouse presentation by Catherine Sutton, Astec's Environmental Compliance Manager.
