Lehigh Valley Transit Book Signing April 14th 1-3pm Emmaus resident Doug Peters became fascinated with trolleys when he was a boy. His lifetime hobby of reading about, researching, photographing and collecting memorabilia related to trolleys led to the publication of Lehigh Valley Transit -- in Color. The book is packed with information on the trolleys and buses that were once the primary mode of mass transportation in the Lehigh Valley. Stop in on Saturday to talk with Doug, and to get your copy of the only book that covers the entire Lehigh Valley Transit Co. operation.
