I found this book great reading! Entertaining, funny, and just right for dipping into on and off. I'm sad it's over. I loved the description of geocaching, and I'm tempted to tru that myself, perhaps a few of the easier ones, since I don't get around as well as once I did. Turning the world into a place of hidden treasures is such a great idea. The book is about all different sorts of map geeks, all brilliantly nerdy and fun. Makes me want to pore over my last road atlas, bought in the 90s, again... or to spend a few hours browsing Google earth.
