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

Sure I have a cell-phone, so I don't have to remember everyone's number anymore, but that really wasn't a core part of my brain.

I remember one of my last shows, the Final Jeopardy! clue was something like 'These two boys' names are top 10 boys' names in the U.S., they both end with the same letter, and they're both names of Jesus' apostles.' Now, obviously that's not a knowable fact.

Knowing lots of answers but being a millisecond slow on the buzzer is indeed very frustrating.

For some reason the most devoted mapheads seem to be kids.

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

Eratosthenes, the mapmaker who was the first man to accurately measure the size of the Earth, was a librarian.
