For years and years, we had a small inflatable globe aboard. It was a $6 impulse buy from a toy shop along our route, and you could tell. Place names were frequently misspelled, and colour fills didn't always match their intended borders. But we had drawn our route on the globe, and it was fun to twirl and look at where we had been.
Alas, our $6 globe was only $6 worth of robust, and developed a leak. It was now a sad deflated thing, sitting in a corner and waiting for me to consign it to the Great Map Collection in the Sky.
And now I can.
