Time Out London Walks Volume 2July 12, 2008 An excellent guide to exploring parts of London that are off the traditional tourist route. Not a criticism of the book but prospective readers should beware that the David Aaronovitch walk number 17 "Sewage and Celebrity" has been curtailed by the development of London's Olympic Park for the 2012 Games. The route is OK up until the Three Mills Pumping Station. During the development of the Olympic Park, this route will not apparently be accessible between the Greenway and Carpenters Road.
