Alastair Bonnett on the world's strangest places

At a time when Google Maps Street View can take you on a virtual tour of Yosemite's remotest trails and cell phones double as navigational systems, it's hard to imagine there's any uncharted ground left on the planet. In his book Off the Map, social geographer Professor Alastair Bonnett goes to some of the most unexpected, offbeat places in the world to reinspire our geographical imagination. His book, Off the Map, is also published under the title Unruly Places.
