The Passport's 'Big Brother' is now in! (don't worry, nothing about the Passport Program has changed, and we're still producing the standard Passport book). The Explorer Edition features a sturdy weatherproof portfolio with a durable inside binder and several pockets for your national park collectibles and personal items. The inside pages are bigger and better than ever, and they're expandable, letting you add or rearrange pages any way you like. The expander pack for the Passport Explorer can be found here.
