Britton Keeshan is using inspiration from Captain Kangaroo in his bid to become the youngest person to climb the tallest mountain on each continent.
Keeshan is the grandson of Bob Keeshan, who died Friday at 76 after a career in which he entertained millions of children as the walrus-mustachioed television captain.
Britton Keeshan, a 22-year-old college student, is on a quest to climb the "Seven Summits," the tallest peaks on each continent. He's reached the top of six so far, starting at age 15, and will leave in March to attempt Mount Everest by May.
