Rest Area Guide

Fairly up to date, obviously things change, but traveling in unfamiliar country, this book is a great help.

Essential reference

This guide is a big disappointment and not at all useful. It lists only rest areas on interstate highways and ignores the many rest areas on other US highways and state highways and roads. A simple Google search: "list of rest areas in (say) Colorado" yields a much complete accounting all rest areas, including the ones on the Interstate.

Liked ,very well written

This guide was so poorly organized that I left it at home while traveling cross county.
