In English lit irony always seemed so complex and difficult, but then Alanis Morissette clarified to a whole generation that irony is rain on your wedding day and a black fly in your chardonnay.I have heard that about Dylan hating Dinkytown, which adds a layer of irony (maybe? I don't remember exactly what irony is) to the people who are nostalgiaing for his tenure here.
Oh, and Bob Dylan is awesome, I'm sure he's worried about preserving Dinkytown ca. 2005 as it currently stands.
