Book excerpt: The first edition of The Great Allegheny Passage Companion told stories of the trail's first 100 miles from McKeesport to Meyersdale. Now author Bill Metzger takes you on a journey along the completed GAP Trail from MP 0 in Cumberland, Maryland to its terminus at Point State Park in downtown Pittsburgh, Pennsylvania. www.greatalleghenypassagecompanion.com The history and heritage of the trail come alive in Bill's inimitable style - humor blends with serious scholarship in this look at the railroads and other industries that preceded the trail's development. No matter when your trail adventure and the book come together you'll understand: What will I see when I get there? This is gonna be great! What am I looking at right now? What did this big concrete thingie used to be? Why did this happen here? Why indeed? What’s on the other side of those trees? Maybe I’ll come back when the leaves are gone. What did I see when I was there? Sorry I missed that. Guess I’ll have to come back again. You'll learn something about the trail and the people of southwestern Pennsylvania - how they lived in Days Gone By and how they made the Passage the wonderful experience it is today.
