National Park Passport stamp collector
Did some searching of the forums, but really didn't find a thread on this topic.
Does anyone else collect National Park Passport stamps?
How do you organize them (use the small blue books, collectors edition, other ways)?
How many have you collected?
Do you collect the "minor" ones, like retired stamps,National Trails, baseball stadiums,lighthouses?
I currently have 113 stamps, and visited 48 official National Park Units.
