Denali National Park has a Junior Ranger program for kids. Families work through a booklet of activities over a couple of days. Then the kid takes their completed booklet to a Ranger, takes a pledge, and recieves a badge. Aiden tells everyone he meets that he is a Junior Ranger...it's part of his identity now! It's a great Kodak moment and worth the effort. I'd encourage anyone with kids to check it out at their local National Park.
