This book gives a very good description of what one can see along the trails but lacks information on intermediate trail access other than what the authors calls the 'Trailhead'. Perhaps some people want to start on the other end or in the middle but there is no description on how to get there. In this age of GPS units in almost every vehicle, GPS coordinates for trail access points are a necessity but none are listed. Some people run shuttles in order to do sections of trails only one way but there is no help, especially for folks that come from far away to ride these trails. The maps are adequate at best. The Office of Greenways & Trails brochures are much better in listing access directions.
