AK passport for Big Kids - what would you do?

[seobaina]

Figured I'd move this to the design threads as it's kinda more a design thing anyway. Thanks to advice on here I've made an EPCOT passport for my friends (adults) for our trip. It's really cute and I know they'll have fun - just a couple of simple things to fill out. They are big kids afterall. Anyway, I was wondering if anyone could think of a fun way to make an AK one? What would you include? Can they get stamped?

Thanks
