This book is based on human performance. Each page represents 250 miles, made up of a 50 mile grid, which is about the distance you can drive in a day. The second scale is a 25 mile square where the grid is 5 miles, ideal for deciding whether to drive through or around a city. The 3rd scale is a 5 miles square with a grid of 1 mile, which allows for street names, major landmarks and hotels. These are all human based maps. The cover is the Table of Contents.
