You can get cancellation stamps at national parks, historic sites, battlefields, historic trails, preserves, and monuments all over the United States. They have the name of the site and the date in which you visited. It’s like a treasure hunt or going geocaching (minus the fancy GPS equipment). The book costs about $8-$10. Our goal on our trip to Virginia is to get cancellation stamps each weekend at some interesting or historic site.
This weekend we decided to go to George Washington’s Birthplace located in Colonial Beach which is in the northern neck of Virginia. It was about a two hour drive from Falls Church which was a little longer than we expected, but it was definitely a great day trip.
