I was in Borders bookstore last night, passing the time before catching the bus. I saw (again, because I had seen it so many times) the book Lost Ann Arbor. After picking it up, I had the same thought that I had many times before: why not do a "then-and-now" photo study of the city? After leafing through the book, I realized that many of the photos (luckily) could be reproduced by a person on foot.
Looking today for the book, I came upon a website of a man who lives here in Ann Arbor (and has presumably lived here for some time), and has some then-and-now photos from around town (not of the University). There are also photos online of historic photos from UM.
