N is for National
The National Park Service has a nifty little Passport book that you can purchase at any one of the 397 National Parks. Did you know there were that many National Parks? I certainly didn't!
The book includes a map of the US showing the location of each park. The book is broken down into regions. Each National Park has a cancellation stamp that visitors may use, at no cost, to document their visit. The stamp names the park and the date.
This is my page for our visit to Casa Grande in Arizona.
Colorful stamps with pictures and information about each park may also be purchased to add to your Passport. I think it is fun to document visits in this way... and I like to think my purchases may support our wonderful National Park system, at least a little bit!
