Book excerpt:  The Appalachian Mountains are a well-known world treasure, perhaps the most biodiverse region on the planet. This book spans almost six years and 500 miles of hiking by the author along the southern portion of the Appalachian Trail. A fresh perspective is brought to the subculture of "AT" hikers. The path of the trail crosses many areas that featured dramatic family events, and the author weaves in compelling stories of his ancestors who called this ancient mountain range home. Also explored are a multitude of topics ranging from environmental challenges to the modern day problems facing residents of the region.
