I have several Atlas's as well as maps from AAA.
At an RV show last fall
I picked up the National Geographic Road Atlas - Adventure Edition
published 2013 for general trip planning.
Its large and the layout is easy to follow - making it easy to use/read. Spiral binding and heavy plastic cover & the pages that seem a bit heavier than other atlas's I have owned making it a bit more durable. I hope.
The front portion of the Atlas gives lots of info on 24 of the more popular National parks across NA as well as historical sites and 100 top recreation areas as picked by the editors of NG Adventure.
It will replace another large format atlas I keep in the trailer (pretty sure its a McNally) that has gotten a bit beat up from use and out of date.
Will still carry my GPS and more detailed maps from AAA if I know in advance where I might be heading.
