I remember reading some of this book while tucked in one of my own cardboard box spaceships, whixh made it even more fun. Of course, my parents worried how I could spend hours on end in a cardboard box, but little did they know my mind was soaring off on amazing adventures. With my canteen full of Goofy Grape soft drink, a peanut butter sandwich, and a good book, I would be ensconced for hours in my make-believe space capsule.
Did you ever do stuff like that when you were a kid? Discuss.
Update: G. W. Ferguson's blog has a delightful recollection of spending some memorable childhood hours in such cardboard boxes; enjoy it here!
