Query: Fantastic! Trail detail with the history of the railroads!

This book is quite unique & even better than the author's previous book on the rail-trails of New England. Three things distinguish this book from others:(1) Insight into the history of the railroads.(2) Useful & reliable descriptions of each trail.(3) Needs of both cyclists & hikers are addressed.A must-have for any rail-trail rider or hiker who wondered about the railroads that once ruled the trail.
