For those of you who visit national parks while on your travels, and also collect the stamps they have available, may I suggest visiting this site to learn more about it: https://www.parkstamps.org/ They have a database that allows you to scan and save your stamps, so if anything were to happen to your book, they are still saved and counted (my count is attached) They even give awards for collecting certain amounts of stamps, and other resources. Thanks, Chris g.
