Although I expected a trivia book--perhaps even a trivial book--Ken Jennings manages to seamlessly weave fun factoids into compelling narratives about geography lovers. Jennings spends time with kids at the National Geography Bee (which is where Alex Trebek dissed American knowledge of geography!). He talks to road geeks who notice differing fonts on various interstate road signs ("Look for the curved tail on the lowercase `l'!"). He touches on about border disputes, gender, brain science, pop culture, politics, history, and religion. In the course of researching for the book he even became addicted to geocaching, a treasure hunting game played by GPS owners all over the world--a pastime which Jennings sees as a human attempt to re-infuse the world with treasure and mystery. "Cartophilia" is alive and well, and Jennings hopes to spread the love: "If you never open a map until you're lost," he insists, "you're missing out on all the fun" (120). His book is a lot of fun.
