The Lincoln Highway, established in 1913 as the first roadway to cross the United States, continues to change. This new second edition of the successful guidebook to the route in Pennsylvania reflects those changes, focusing on recent trends on the highway, such as the appearance of retro buildings. The book describes what life was like along the old highway -- with its stainless-steel diners, mum-and-dad businesses, spectacular scenery, and roadside attractions -- and reveals how much of the past is still around.
