Ken Jennings (of Jeopardy fame) delivers a fantastic sampling of the geo-geekdom. From map lovers (where it starts) to geography bees to road geeks, to obsessive travel, to geo cachers to Google Earth's transformation of the paper to cyber world of finding where you are and devoting a great deal of energy to it. Jennings is entertaining, literate (if not annoying in his constant referrals to pop culture as well as history.) but most of all he, like me, LOVES maps. And if you LOVE maps, this is a four, if not five star, book, just to find those fellow oddballs who find order in the universe looking at a map. Honey, I won't ask for directions because I get to follow the map. Why would I? His arguments for the spatial development of the brain as a product of map love are interesting but not as interesting as the stories about the people who've been to the highest point in all 50 states. And that's the revelation about this book: people are still in love with finding things. The earth is their treasure hunt. And that's fun!
