If I start outsourcing all my navigation to a little talking box in my car, I'm sort of screwed. I'm going to lose my car in the parking lot every single time.

People are using GPS systems to find millions of little hidden objects throughout the world - often as simple as a piece of Tupperware hidden in the woods. You go to a website, you get the latitude and longitude to get the specific location of a certain specific hiding space, and then you go there and see if you can find it.

For me, it started as a child with one of those little wooden jigsaw maps of the U.S., where's there's crocodiles on Florida and apples on Washington state. That was my very first map.

I have condemned my kids to a lifetime of geographic illiteracy.

You live overseas, you see these exotic places and you want to know about them. But, weirdly, it also made me homesick for all these very prosaic places in America.
