Ken Jennings is known for being one of two carbon-based contestants to match wits with IBM's "Watson" supercomputer on "Jeopardy!" last February. Machine bested man in that game, but Jennings nevertheless holds two game show records among humans – longest winning streak on Jeopardy! (74 games) and all-time biggest money winner on U.S. game shows ($2.52 million).
He's also a self-identified "geo-geek" whose fascination with cartography led him to sleep with a Hammond World Atlas under his pillow as a child. In his new book, Jennings takes us on a journey into geography itself, delving into the history and culture of maps, mapmakers and map lovers. From the parchment maps of the Age of Discovery to the post-modern world of GPS-cachers, Jennings shares his sense of geo-curiosity with an entire planet of explorers, wanderers and pathfinders. In honor of Geography Awareness Week, we welcome Ken Jennings to answer your geo-questions. Are you a maphead? Do you swoon over old trails and lost highways? When you travel, do you prefer to plan out your route, trust in your Tom-Tom, or just follow the signs? Where do your favorite maps take you?
