I thought this would be mildly interesting, because of the Canadian connection (Tubman brought her family to Upper Canada, and lived in St. Catharines for a time, though she returned fairly quickly to New York State), but it turned out to be more than that. Not having had an American upbringing, I had only the haziest notion of what life was like in pre-Civil War and Civil War times. And although I had seen Tubman's name here and there, I had no notion of what a downright hero she really was. Both of these states of ignorance are now substantially corrected!
