They were three, five and seven at the time. We were flying from Seattle to Amsterdam and our three year old decided to stay awake until he'd seen London from the air. On arrival we lost our five year old, who decided to go to the bathroom by himself and lost his way. It was awhile before airport security found him checking out a litter of St. Bernards labeled to Cape Town. It was then that I decided next time we'd fill backpacks with fun and interesting activities. Learn the ropes. Make a shell frame, a necklace. Rubber stamp a story on a blank page. Prepare a message in a bottle, imagining where it might beach... One new box for every waking hour of travel, it would have made for a fun and rested arrival. Compact, interesting, hours of interactive fun.
