Given a wide choice of local, regional, and national history, I seem to have been drawn to books on water. (Maybe it’s time for a camping trip?)
971.315 A Respectable Ditch: A History of the Trent-Severn Waterway, 1833-1920, by James T. Angus (1988). [How can you resist a title like that?]
971.699 A Dune Adrift: The Strange Origins and Curious History of Sable Island, by Marq de Villiers and Sheila Hirtle (2004).
977 The Living Great Lakes: Searching for the Heart of the Inland Seas, by Jerry Dennis (2003).
